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.
Why Shipping Several Similar Apps Triggers App Store Guideline 4.3 — Differentiation for Indie Developers
Ship a few similar Rork apps and you may run into App Store review Guideline 4.3 (Spam). Here is why it happens more with AI-generated apps, how to differentiate before you submit, and how to respond if you have already been rejected — from an indie developer's point of view.
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.
An Honest Review of the Rork AI App Builder After Three Months — Strengths, Weaknesses, and Who It's For (Revisited July 2026)
A no-spin review of the Rork AI app builder from a solo developer who shipped to the App Store with it and kept using it for three months. What was fast, what surprised me, how to judge the pricing, and who it actually fits.
