Stop Spinning Up a Separate Server: Colocate Your Backend With Expo Router API Routes
Standing up yet another Worker just to receive a RevenueCat webhook gets old fast. Expo Router API Routes let you put the backend inside the same repo as your app. Here is the implementation, from signature verification to picking a deployment target.
The Generated Screen That Quietly Jams at AX5 and in German — Putting Layout Resilience Checks on Rork Max SwiftUI
A record of running every Rork Max generated SwiftUI screen through pseudolocalization and the largest text size to find exactly where it jams. Covers when to reach for ViewThatFits, ScaledMetric and layoutPriority, plus the snapshot checks that catch regressions every time you regenerate.
Your AR Furniture Is Gone by Morning — Persisting Placements with ARWorldMap
AR apps generated by Rork Max lose every placed object on relaunch. Here is the design that fixes it: when to save an ARWorldMap, how to encode custom anchors, how to handle the relocalization wait, and what to do when relocalization simply never lands.
Shipping Notifications Without Asking First — Provisional Authorization in Rork Apps, and the Expo Snippet That Quietly Undoes It
iOS lets you start delivering notifications with no permission dialog at all, via provisional authorization. The catch: expo-notifications reports granted as false for provisional devices, so the registration snippet in Expo's own docs re-requests permission and fires the very dialog you were avoiding. Here's why granted lies, a hook that models authorization as five states, how to write notifications for quiet delivery, when to ask for the upgrade, and how to keep provisional out of your CTR.
The Update That Failed Because a Profile Expired Three Months Ago
Apple signing assets expire quietly and nothing tells you. Here is how to count the days left with the App Store Connect API and put the audit on a weekly Cloudflare Workers cron.
Killing the Export Compliance Prompt in Rork Builds for Good
Every Rork and Rork Max build lands in App Store Connect with a Missing Compliance warning. Here is how to decide whether you qualify for the exemption, and how to set it once in app.json or Info.plist so the question never returns.
Regenerable Zones in Rork Max Code: Keeping the Freedom to Rebuild
Generated code carries an invisible asset: the option to throw it away and rebuild it. Every hand edit quietly expires that option. Here is how I track it with a ledger and CI checks across six live apps.
Test Generated Purchase Code Before You Touch Sandbox — Automating Refunds, Expiration, and Failures with SKTestSession
Rork Max generates StoreKit 2 code that proves people can buy. It does not prove refunds, expiration, or failed purchases are handled. Here is how to cover those paths with SKTestSession before you ever open Sandbox.
A Yellow Warning in Dev, a Crash on Resume — Functions in Route Params
Rork generated navigation code that put a function and a Date into route params. In development it was only a warning. After the OS reclaimed the process, resuming the app crashed with params.onFavorite is not a function. Here is the cause and the fix.
The Comma That Fell to the Start of a Line: Rork, Quote Cards, and Japanese Line Breaking
React Native's Text component does not guarantee Japanese line-breaking rules. Here are the violation rates I measured, a WORD JOINER implementation that survives copy and VoiceOver, an onTextLayout audit harness, and how Rork Max (SwiftUI) differs.
Half the Bytes, the Same Wait: What AVIF Actually Cost My Wallpaper Apps
Switching to AVIF cut my transfer bill in half and did nothing for perceived speed. Here is the transfer-versus-decode breakdown, the Accept-negotiation trade-off, per-device fallback tiers, and the staged migration order that finally worked across six apps.
My Rork sleep timer faded out on time — but the sound didn't
Rork writes sleep-timer fades against the wall clock with setInterval. The numbers say 30 minutes, but the real audio fades early or cuts out abruptly. Here is how to drive the fade from the actual playback position, why a logarithmic curve sounds natural, and the honest limit of JS fades when the screen is locked.
Designing Seams That Survive AI Regeneration in Rork
Every follow-up prompt to Rork can quietly wipe out logic you wrote by hand. Protecting it with prompts is a patch, not a fix. Here is how to separate generated code from code you own, and draw a boundary that regeneration cannot reach, with working Zustand and service-layer examples.
Adding a Single Zod Validation Boundary to Rork's Generated Fetch Code
The network code Rork generates implicitly trusts the shape of the response. When the API shifts, the screen quietly goes blank. Here is how to slip a single Zod parse layer between the generated UI and the network to make failures predictable, with numbers from real operation.
postMessage Is Fire-and-Forget — Designing a Correlated Request/Response Bridge Between a WebView and React Native
postMessage between a WebView and React Native is one-way, so you never learn whether the work you asked for actually succeeded. Here is a typed request/response bridge, with correlation IDs and timeouts, built in working TypeScript.
When "{n} items" Breaks Across Languages — Designing Quantity Strings with CLDR Plural Categories and Intl.PluralRules
The assumption that one is singular and everything else is plural falls apart in Russian and Arabic. Here is how to hold the CLDR plural categories as a map and render quantities correctly with Intl.PluralRules and i18next, drawn from localizing an indie wallpaper app into sixteen languages.
Your Detox and Maestro E2E Suite Was All Green — but the Retries Were Hiding a Flaky Test That Crashed in Production
Your E2E suite is green, yet production still crashes. The culprit: auto-retries quietly swallowing flaky failures. Field notes on measuring per-test flake rate, quarantining, and keeping only real failures as release gates.
Losing HealthKit Data on Incremental Sync — Designing HKQueryAnchor Persistence
When step or sleep data double-counts or goes missing on incremental HealthKit sync, the root cause is usually HKQueryAnchor persistence. Here is a working Swift design that handles newAnchor and deletedObjects correctly and stays consistent across reinstalls and background updates.
A symbolEffect Field Memo: Making Icons Move Nicely in Your Rork Max App
Animate SF Symbols in a Swift app generated by Rork Max using bounce, pulse, variableColor, and contentTransition, with working code, OS-version gating, and the mistakes I made from over-animating.
Undo That Jumps to the Wrong Place — Designing Edit History You Can Trust
Snapshotting the whole state on every edit crushes memory after a few dozen steps. Here's an undo/redo built on command history plus snapshots, with coalescing, a depth cap, and cross-session persistence, in working TypeScript.
Implementing App Clips with Rork Max — delivering the core of your app the moment someone scans a code
Building on the native Swift that Rork Max produces, this note walks through the 15 MB App Clip budget, receiving the launch URL, and handing state off to the full app.
The Device Clock Can Be Moved — Protecting Daily Features and Trial Logic from Time Tampering
Advancing the device clock by one day was enough to claim tomorrow's daily wallpaper today. Starting from that log entry, this article lays out a three-layer time model — wall clock, monotonic clock, server time — and shows how to build daily-reward and trial logic that survives clock rollbacks.
When Sentry Burned Through Its Event Quota in Days — Trimming Noise Before It Ships
A Sentry quota that empties early in the month is almost always a noise problem, not an error surge. Here is how to shrink event volume before it ships — with beforeSend, sampling, and grouping — while keeping the errors that actually matter inside the quota.
Verifying StoreKit 2 Signed Transactions in a Cloudflare Worker
If you trust whatever the device says about its purchase state, a tampered entitlement walks right through. This walks through verifying StoreKit 2 signed transactions (JWS) in a Cloudflare Worker so you grant entitlements without trusting the client, with working code.
Adding React Compiler to Expo Let Me Delete 41 Hand-Written memo Calls
I enabled React Compiler on Rork-generated React Native screens and measured the rerender counts with Profiler. Here is how I decided which memo and useCallback calls were safe to delete, how to find the components the compiler bailed out on, and how to catch regressions in CI.
The Termination That Never Shows Up as a Crash — Reading JetsamEvent in Rork Apps
Crashlytics is silent, yet reviewers write that the app closes by itself. Most of the time the OS killed it for exceeding its memory limit. Here is how to read JetsamEvent reports and design an image-heavy app's memory budget from measured values.
Every Key You Ship Is Public: Secret Boundaries and Rotation for Rork-Generated Apps
Unzip your own .ipa, run strings, and your environment variables are right there in plain text. Here is how I sort keys into three tiers, move the dangerous ones behind an edge proxy, and keep a rotation runbook that assumes leakage.
Getting Rork Max's Swift Through Swift 6's Strict Concurrency Checking
A field record of taking a Rork Max-generated SwiftUI app through Swift 6 complete concurrency checking: 217 warnings cleared target by target, where @MainActor actually belongs, and measured before/after numbers.
Holding Layer Boundaries in a Rork-Generated Expo App with ESLint and dependency-cruiser
Long-lived Rork-generated Expo apps quietly accumulate screens that import the API client directly. Here is how I froze 214 existing violations as a baseline, eliminated 17 circular dependencies, and made CI reject anything new for 38 extra seconds.
When Amplitude's Funnel Improved Overnight — Field Notes on Catching Event Schema Drift With a Self-Audit
In a Rork-built app, the Amplitude funnel showed signup-to-purchase conversion jumping from 8% to 19% overnight, yet revenue stayed flat. The cause was a property-name drift that inflated the count. Field notes on measuring the drift with an event contract and a runtime validator, then tightening it in stages.
Your SVG Icon Shows in Expo Go but Vanishes in a Build — Making SVGs Render Reliably in Rork Apps
When a .svg import renders nothing, throws a resolve error, or ignores your theme colors in Rork and Expo apps, here is how to fix it with metro.config.js, react-native-svg-transformer, and currentColor — with working code.
Building a Segmented Control With a Sliding Indicator in Reanimated
The stock segmented control looks out of place on Android. Here is a custom Reanimated component that measures each segment and slides the indicator, with complete code plus UI-thread rendering, accessibility, and RTL handling from real shipping notes.
Working Around Rork Max's 20-Geofence Wall with Dynamic Re-registration
In a native Swift app generated by Rork Max, geofences you registered quietly stop firing past a certain count — and it's almost always iOS's silent limit of 20 monitored regions per app. Here's a dynamic re-registration design that keeps only the nearest 20 live, plus a Swift implementation you can drop in.
When the Device Runs Out of Space, What Should Your App Protect?
Design Expo/React Native apps that assume writes can fail. Free-space budgets, LRU reclaim, data-protection tiers, and telemetry that surfaces silent failures — drawn from running six wallpaper apps.
The App Icon Badge Still Says 3 — Rebuilding Expo Badge Counts Around a Single Source of Truth
Why an Expo app's icon badge drifts out of sync with real unread counts and refuses to clear — and how to rebuild it around a single source of truth, with working recompute-and-sync code and the production pitfalls that bite you.
When In-App Review Prompts Fire but Your Ratings Never Move — Field Notes on Measuring Display Opportunities and Timing
You wired expo-store-review into your Rork app, yet the star count won't grow. The OS silently suppresses the dialog, so calling it doesn't mean it shows. These are field notes on measuring display opportunities and redesigning timing.
Which Generation Introduced This Bug? Building Provenance Into Rork Apps
When you regenerate the same screen again and again with an AI builder, a bug that shows up one day becomes impossible to trace to a specific generation. This is a design for keeping generation provenance across three layers—build stamp, ledger, and telemetry—so you can narrow a regression down to a single generation in minutes.
Migrating Rork Max SwiftUI to @Observable: Narrowing the Re-renders ObservableObject Was Spreading
Rork Max tends to generate SwiftUI apps built on ObservableObject and @Published, where a single state change re-evaluates every subscribing view. Moving to the Observation framework's @Observable narrows invalidation to the property level. Here is the migration path, plus the view-body execution counts I measured in Instruments before and after.
Opening Your Rork Max App to Apple Intelligence — Designing App Intents Assistant Schemas and Handling What Doesn't Fit
How to make actions in a Rork Max-generated Swift app callable from Apple Intelligence using App Intents Assistant Schemas — mapping to the fixed schemas, routing what doesn't fit, availability fallbacks, and on-device testing.
Cloud-Synced Folders Break App Builds — Excluding Build Artifacts From Sync to Fix It for Good
A project living in Dropbox or iCloud Drive stopped building one morning. The cause was sync creating conflicted copies inside build artifacts. Here is how I excluded node_modules and Pods from sync to stop the recurrence, told as an indie developer's field notes.
Changing a Table Without Wiping User Data in Rork's expo-sqlite — A PRAGMA user_version Migration Runner
A crash on launch, only for existing users: no such column. That is what happens when you ship a table-structure change to installs that still hold the old schema. Here is the expo-sqlite migration layer I put in every Rork app, built on PRAGMA user_version, with the full runner and the operational rules behind it.
Your Rork Max App Loses the Photos a User Picked After Relaunch — The Trap of Holding Onto URLs Under Limited Photo Access
In a native Swift app generated by Rork Max, photos picked via PHPickerViewController become unreadable after relaunch — because holding onto a URL or PHAsset no longer works in the age of limited access. Here's a design that copies the actual bytes into your own storage the instant they're picked.
Start a Live Activity Without Launching Your Rork Max App — Designing Around a push-to-start Token That Never Arrives
In a native Swift app generated by Rork Max, you want to start a Live Activity from your server without the user ever opening the app. But the push-to-start token is never observed and it fails silently. Here's the cause and an observation layer that reliably captures the token.
Your Rork Max Health App Misses Overnight Steps — Designing Background Delivery When HKObserverQuery Dies Silently
In a native Swift health app generated by Rork Max, data recorded while the app is closed never arrives — and it's almost always because HKObserverQuery's background delivery stopped without a word. Here's how to isolate the layer that broke and an observation layer you can drop in as-is.
Direct Device-to-Device Sharing in Rork Max Apps — The Local Network Permission Trap That Makes MultipeerConnectivity Fail Silently
How to add serverless, nearby device-to-device sharing to a native Swift app generated by Rork Max. It works in the simulator but no peers ever appear on real devices — and the culprit is almost always a silent Local Network permission failure.
Should You Show a Read More Link? Let the Rendered Text Decide in Rork (Expo)
Clamping a product description to three lines and adding a Read more toggle sounds simple, until the toggle also appears under single-line text. This walks through measuring the real line count with onTextLayout so the toggle only shows when text actually overflows, covering iOS vs Android quirks, expand animation, and font scaling.
When Your App Store Connect API Pipeline Quietly Drops Days — Field Notes on JWT Expiry, Report Lag, and Reconciliation
Automated App Store Connect API pipelines rarely stop — they leak. This piece breaks down the three silent failure modes behind 401, 404, and 429, and shows how a fetch ledger, a 72-hour backfill window, and a weekly reconciliation query keep daily sales and review data complete.
When a Rork Video Call Is 'Connected' but Only One Side Can Hear — Field Notes on Instrumenting WebRTC's Silent Failures
Rork video calls that go one-way or quietly drop on the subway, diagnosed by measuring WebRTC with getStats instead of guessing. Covers ICE restart, verifying TURN relay, and clean teardown.
Rork Max Cloud Compilation — Shipping Native Apps Without Owning a Mac
How Rork Max's cloud compilation lets you build, device-test, and publish native iOS/iPadOS apps without a local Mac — including how to triage failed builds and when you should still keep a real Mac around.
Take One Contact, Not the Whole Book — iOS 18's ContactAccessButton
iOS 18 adds a limited tier to contacts access. With ContactAccessButton you can receive just the one contact a user picks, without ever asking for the whole address book. Assuming the native Swift Rork Max generates, here is the design and implementation.
Answering a Refund Request Within 12 Hours: Handling CONSUMPTION_REQUEST in Cloudflare Workers
How to receive the App Store CONSUMPTION_REQUEST notification for your Rork subscription app in Cloudflare Workers and respond to the Send Consumption Information API within 12 hours — with field-by-field mapping and the operational judgment behind it.
Adding Home-Screen Quick Actions to a Rork App — dynamic items without cold-launch drops

How to add a toolbar pinned above the keyboard — a Done button or quick-insert actions — to the React Native app Rork generates. The iOS InputAccessoryView and a hand-built Android bar, folded into one reusable component, with working code.
Handling iOS Limited Photo Library Access in a Rork (Expo) App
Handle iOS limited photo library access (selected photos only) correctly in a Rork (Expo) app. Covers the three states of full / limited / denied, designing a screen that works from the selected subset, and a path to add more photos, all with working code.
When a New Architecture Migration Only Janks in Release Builds — Field Notes on Catching Silent Interop-Layer Fallback
A Rork app on the New Architecture scrolled fine in development but stuttered only in release builds on real devices. The cause: a legacy native module quietly falling back to the interop layer. Field notes on measuring it and rolling out a fix without reverting the whole app.
Rork × Vision Camera v4: A Production-Grade Camera Stack with QR, OCR, and ML Inference
Wire React Native Vision Camera v4 into a Rork project end-to-end — frame processors, ML inference, QR/OCR, plus battery and thermal tuning, a real-device test matrix, store review, and a staged rollout.
Write to NFC Tags with Rork Max: Add a Step Beyond Read-Only
The NFC apps Rork Max generates usually start with reading. But the experience really changes when you add writing. Here is how to write NDEF to a tag with CoreNFC, plus the pitfalls you can only catch on a real device.
Ship EAS Updates to a Few First, and Halt Automatically on Crash Rate
Because OTA updates reach everyone instantly, a bad update reaches everyone instantly too. Here is a three-layer design: ship EAS Update to a small canary, decide expand-or-halt from crash-free rate automatically, and hold a safety net on the device — with working code.
When your Rork app's production crashes arrive minified — wiring Hermes source maps and debug IDs into Sentry
Rork-generated Expo apps run on Hermes, so production crashes often arrive as index.bundle:1:284913 with no function names. Here is how to wire Hermes source maps and debug IDs into Sentry so your stack traces become readable.
What Rork's Browser Live Simulator Can Verify — and What Belongs on a Real Device
Rork's in-browser live simulator collapses the build-test loop dramatically, but it can't judge everything. Here's a clear, item-by-item split between what the simulator is enough for and what you must move to a real device through Companion.
Build Your Settings Screen From One Schema and Reuse It Across Apps
Hand-building a settings screen per app falls apart as your app count grows. Here is a schema-driven design that assembles the screen from declarative data and shares a common base across multiple apps, with working code.
Before a Free Preview Walks Out via Screenshot: Detecting Screenshots and Screen Recording in Rork/Expo
How to protect paid preview images from screenshots and screen recording in a Rork/Expo app: the limits of expo-screen-capture, native isCaptured monitoring, and an iOS/Android-aware blur design.
When Your App's Launch Got Quietly Slower Release After Release — Field Notes on TTI Instrumentation and a Startup Budget for Rork Apps
Rork apps tend to start fast on day one, then drift slower as you add features and SDKs. These field notes show how to catch cold-start regressions that averages hide, trace them to a release, and stop the drift with a CI startup budget.
Catch Real-Device Bugs Before You Ship: A Pre-Submission Checklist for Rork Share Links
Rork's editor preview runs in an ideal environment, so it hides bugs that only appear on real hardware. Here are the seven device differences to clear before you hand out a share link, in the order to check them, with the code to set up first.
Keep Your Rork App's Review From Stalling on a Privacy Manifest Gap
Handle PrivacyInfo.xcprivacy and Required Reason APIs in a Rork Expo app — a common cause of App Store review stalls — with the app.config.ts setup and a step-by-step check of third-party SDKs.
Watermark Only the Shared Image in Your Rork Wallpaper App
In a Rork-generated Expo wallpaper or image app, keep saved images untouched and burn a watermark only into the share export, shown two ways — react-native-view-shot and Skia — with the resolution-loss pitfalls to avoid.
Show Your Rork App's Progress on the Lock Screen and Dynamic Island
Add Live Activities and ActivityKit to a Swift app generated by Rork Max so a meditation timer or delivery status appears on the lock screen and Dynamic Island, with working code and the submission gotchas to watch for.
Import the User's Own Image From the Files App in a Rork App, Without the URL Going Stale
Pull images from the Files app or iCloud Drive and the URL you picked goes invalid moments later. Here is how expo-document-picker, security-scoped URLs, and a reliable copy into your sandbox actually work, with running code.

How to make a Rork-generated Expo app keep playing music or healing sounds in the background and expose lock screen and Control Center controls, with working expo-audio code and the platform-specific gotchas.
When Push Notifications Reach Only Some Users — A Delivery-Reliability and Diagnosis Design for Rork (Expo) Apps
A design for diagnosing why push notifications reach only some users in a Rork-generated Expo app, by splitting send-to-display into stages and measuring delivery to close the gap. Covers stale-token cleanup, recording APNs/FCM failure codes, priority and message type, and a per-user triage procedure, with implementation.
Why Your 9 AM Reminder Stops Arriving Abroad — Making Expo Local Notifications Survive Time Zones and DST
Daily reminders built with Rork (Expo) can drift to the wrong local time when users travel or DST flips. Here is the timeInterval trap, and a design that reschedules against local wall-clock time, with working code.
Why Paying Members See a Paywall in Airplane Mode — Keeping RevenueCat Entitlements Alive Offline
Open the app on a weak connection and a paying subscriber sees a paywall flash for a second. Here is how RevenueCat's customerInfo wavers on an offline launch, and a cache design that keeps entitlements valid with a trust window — written as working code for an Expo app.
Keeping Your Rork App's Expo SDK Upgradable Year After Year — Release Trains and Regression Safety Nets
A maintenance design for keeping Rork-generated Expo apps running through yearly Expo SDK upgrades without breakage. Covers release-train cadence, dependency pinning, regression safety nets, and splitting OTA from store delivery, with real examples.
When an Image-Heavy Rork App Quietly Bloats Its Cache and Dies on Memory — Field Notes on Measuring and Capping
In a Rork app where images are the product, expo-image's disk cache and resident memory creep up over a session and surface as OOM crashes. Here's how I measured the bloat, where I set caps, and what I trimmed on the delivery side — with working code, in the order that actually helped.
Fixing Stutter When a Rork Max SwiftUI Image Grid Scrolls
Measure why a Rork Max SwiftUI image grid stutters while scrolling, then fix it with ImageIO downsampling, off-main-thread decoding, and stable cells to cut real-device hitches.
Audio Apps That Survive Calls, Unplugged Headphones, and Other Apps Taking Over
How to handle AVAudioSession interruption and route-change notifications correctly so playback survives calls and headphone unplugs, with working Swift code.

How to watch ProcessInfo's thermalState and Low Power Mode and degrade heavy work in stages when the device is hot or the battery is low, with working Swift code.
When EAS Update Ships but the Bug Won't Die — Why OTA Stalls Silently, and How I Operate Around It
EAS Update can succeed and still fail to reach a slice of your users. These are field notes on runtimeVersion drift, updates that publish but never get adopted, and choosing the right rollback — with the instrumentation that actually helped on my Rork apps.
Building a Breathing-Paced Haptic for a Meditation App with CoreHaptics
Canned expo-haptics buzzes can't produce the swell of a breath. Here is how to call CoreHaptics continuous events and parameter curves from an Expo native module to build a haptic synced to 4-7-8 breathing, with working Swift and TypeScript code.
The Post You Wrote Offline Shows Up Twice — Designing a Send Outbox That Survives Retries
Persisting a queue and replaying it isn't enough — a lost response turns into a duplicate write. Here's a send outbox with idempotency keys, temp-to-server ID remapping, and poison-message quarantine, in working TypeScript.
What Your App Should Do When Someone Turns On Reduce Motion — A Motion-Respecting Layer in Expo
When a user enables iOS Reduce Motion or Android Remove Animations, how should your app respond? Combine AccessibilityInfo with Reanimated's ReduceMotion to replace heavy motion with a calmer alternative instead of simply switching it off.
DAU Went Up but Retention Didn't — Rebuilding Gamification That Actually Sticks in Rork Apps
Points, badges, and leaderboards lift DAU, but retention is a different story. Field notes on a server-authoritative point ledger, streaks that forgive, and leaderboards that don't crush newcomers — with working code for Rork apps.
Why Your Prices Show as “¥1234” on Some Phones — A Formatting Layer That Doesn't Trust Intl Alone in Expo
Same code, yet one device shows “¥1,480” and another “¥1480.” In Expo / Hermes, Intl leans on each device's locale data, so output can drift by OS and engine. Here is a resilient formatting layer that centralizes currency, number, date, and timezone handling and falls back gracefully where Intl is incomplete — with working code.
The Private Screen That Lingers in the App Switcher — Hiding the Snapshot iOS Takes the Moment You Background Your App
When you send a React Native app generated by Rork to the background, iOS photographs the current screen for the App Switcher and writes it to disk. Journals and personal input screens linger there in plain sight. This walks through the iOS privacy overlay (why inactive, not background), Android's FLAG_SECURE, scoping it to sensitive screens only, and screenshot detection — all in working code.
When a Poisoned Cache Crashes Your App on Every Launch — Designing a Safe-Mode Boot Your Users Can Escape On Their Own
When a persisted cache goes bad and the app crashes at the same spot on every launch, the only option left to the user is to reinstall. This article designs a safe-mode boot for Expo (React Native): the app counts its own early crashes, confirms a launch only once it becomes interactive, and resets just the dangerous state in graduated steps.
Your Daily Reminder Stops Firing After a Couple of Weeks — iOS's Invisible 64-Notification Cap
When a daily reminder built with Rork (Expo) goes silent after a while, the cause is usually iOS's 64 pending-notification limit. Design a repeating calendar trigger for fixed messages and a rolling reschedule for daily-changing content, with working code that survives DST and multiple reminders.
Build a Toast System in Your Rork App That Survives Overlaps, Screen Readers, and Notches
When you add toast notifications to a React Native app generated by Rork, the naive version breaks in three places: two toasts overlap, screen readers stay silent, and the text hides under the notch or home indicator. This walks through a root-level queue, animations decoupled from your app tree, AccessibilityInfo announcements, and safe-area placement — all in working code.
Serving Both Plain Rork and Rork Max From One Backend — Designing an API Response Contract That Never Breaks Old Binaries
When plain Rork (React Native / Expo) and Rork Max (native Swift) both call the same Cloudflare Workers backend, the whole design centers on not breaking old binaries you cannot force-update. Wrap responses in an envelope, evolve them additively, absorb client differences with capability flags, and retire old contracts safely — shown in code.
Hardcoding Your OpenAI Key in a Rork (Expo) App Means It Gets Stolen — Slip a Thin Worker Proxy In Between
Embed an OpenAI or Gemini API key directly in the Expo app Rork generates and it can be extracted from the shipped binary. Here is why a key inside an app is never secret, plus a minimal Cloudflare Workers proxy that hides it (streaming passthrough included), simple abuse controls, and key rotation that needs no app review.
Your Rork App's Photos Look Sideways Only After Upload — Normalizing EXIF Orientation and Stripping Location Metadata
A photo that looks upright in your app rotates 90 degrees once it hits your server. The cause is the EXIF Orientation tag. Here's how to bake the rotation into pixels and strip location metadata with expo-image-manipulator before uploading.
Reclaiming the Pre-Submit Checks You Lose When Publishing Without Xcode
Rork Max's two-click publishing skips the Xcode Organizer, making it easy to miss usage strings, version bumps, and Bundle IDs. Here is a quick pre-submit self-audit you can run yourself, with how to read the generated files.
Your Notification Opens the App but Lands on Home — Routing Rork Apps by Launch State
How to make a notification tap reliably reach its target screen. We cover the three launch states — killed, background, foreground — and a pending-route design that never drops a tap that arrives before navigation is ready.
Where Should Your Rork App Store Auth Tokens? expo-secure-store and a Biometric Gate
How I moved a Rork-generated app's auth tokens out of AsyncStorage into expo-secure-store and put a biometric check in front of every read — including the size limit and sign-out gotchas I hit in production.
Add Long-Press Drag Reordering to Your Rork Favorites List Without the Jank
A practical walkthrough for retrofitting long-press drag reordering onto a Rork-generated favorites list: keeping re-renders down, respecting the worklet boundary, persisting the order, and avoiding ghost cards and scroll conflicts.
Why "Save to Photos" Fails on Only Some Devices in Your Rork App — expo-media-library Permission Scopes and Save Design
Your Rork app's image-saving feature works perfectly on your phone but fails for a subset of users. The real cause is expo-media-library permission scopes. Here is a save flow and album design that handles writeOnly permission, iOS limited access, and Android 14 partial access.
What to Decide Before Spreading One Idea Across Every Apple Platform
Rork Max can generate native Swift for iPhone, iPad, Apple Watch, Apple TV, and Vision Pro from a single idea. But 'can ship to all of them' and 'should ship to all of them' are different things. From an indie developer running several apps, here's a framework for choosing which devices to add and which to skip, reasoned backward from operating cost and usage context.
Why Your Rork List Starts Duplicating and Dropping Rows as It Grows — Cursor Pagination and Resilient Refetch State
The naive offset pagination Rork scaffolds for you quietly breaks the moment your list changes underneath the user. Here is how to move to a cursor contract, fold every fetch state into one usePaginatedList hook, and recover failed page loads with exponential backoff — implementation first.
Bugs Rork Can Fix vs. Bugs You Should Fix Yourself: A Triage Workflow for Exported Code
A practical triage workflow for telling apart the bugs Rork resolves on its own from the ones you should hand-fix in exported React Native/Expo code, with working examples.
Hardening API Calls in Rork Apps: Token Refresh, Retry, and Idempotency
The fetch Rork generates is left fragile against expired tokens, flaky signal, and double sends. Here is a design that consolidates token refresh, retry with backoff, and idempotency keys into a single client layer, with implementation code and operational numbers.
Rebuilding Rork's Generated Form Screens for Real Use: react-hook-form and zod
Rork's generated forms look fine on screen but fall apart on a real device: the whole screen re-renders on every keystroke, the keyboard hides the submit button, and slow networks invite double submits. Here is how I rebuild them with react-hook-form and zod, from an indie developer's point of view.
Logging Design for Rork Apps: What to Keep and How to Redact PII
Rork-generated apps tend to scatter console.log everywhere, and when a bug appears you cannot read the part that matters. This designs structured logging, log levels, automatic PII masking, and production send control — all with code you can use as-is.
When Rork-Built Lists Stutter: Designing Image Caching and Prefetch
A FlatList from Rork starts stuttering once the images pile up. Here is how I restore smoothness with expo-image caching, recyclingKey, prefetch, and a move to FlashList, with the device numbers I measured.
Adding a Minimal Test Safety Net to Rork-Generated Screens
You add one new screen to a Rork app, and a completely unrelated paywall check quietly breaks. This is how to bolt a minimal automated test safety net onto generated code with Jest and React Native Testing Library — protecting only the three places that hurt when they break.
Make ITMS-91053 Stop Catching Your Rork Max App — A Release-Proof Privacy Manifest Workflow
