One Month of Reading Xcode Organizer Hang Reports Only on Friday Afternoons
I switched to reading Xcode Organizer Hang Reports for only thirty minutes every Friday for a month. Here is how it compared with Crashlytics and what actually improved across my wallpaper apps.
Implementation Notes: Adding StoreKit 2 In-App Purchases to a Rork iOS App
Notes from grafting StoreKit 2 in-app purchases onto Swift/SwiftUI code generated by Rork, drawing on the StoreKit 1-to-2 migration done across a 50M-cumulative-download wallpaper-app portfolio. Covers ProductID design, transaction verification, paywall UI, and production gotchas.
iOS Memory Pressure on Rork Apps — A 5-Tier Release Architecture from 12 Years of Wallpaper Apps
A 5-tier memory release architecture for Rork-built iOS apps, refined while running wallpaper apps to a cumulative 50 million downloads. Includes the Instruments + MetricKit measurement flow that brought OOM rate from 4.3% to 0.36%.
Adding AppLovin MAX to a Rork-Generated iOS Project — A Field Note on Init Order, ATT Consent, and eCPM A/B Testing
A field note from an indie developer on layering AppLovin MAX on top of a Rork-generated iOS app: SDK initialization order, ATT and MAX consent flag sync, and a minimal A/B setup to compare eCPM against AdMob-only.
Why your Rork app shows a blank screen or loses state after returning from background
Your Rork app sits in the background overnight, you tap the icon the next morning, and the screen is blank — or your drafts have disappeared, or you have been silently logged out. iOS process reclamation, AsyncStorage rehydration timing, and Navigation state restoration each cause a different version of this bug. Notes from running wallpaper and wellness apps with 50M downloads as an indie developer.
Rolling Out Privacy Manifest to Six Wallpaper Apps in Parallel — Translating One Rejection into Five Clean Submissions
Operational notes from rolling out Privacy Manifest to six iOS wallpaper apps in parallel. How a single rejection on the first submission shaped the remaining five, and how phased release rings were designed for a UI-less update.
Enforcing AI Cost Ceilings at Runtime — A Budget-Guard Architecture for Rork Apps
How to stop runaway AI bills not by optimizing, but by physically enforcing budget at runtime. An indie developer's three-layer architecture using Cloudflare Durable Objects, with hard-won lessons from running 50M-download apps.
Staged migration of a Rork-generated RN project to the New Architecture — notes from running six wallpaper apps in parallel
An implementation log for incrementally enabling Fabric and TurboModules on a Rork-generated React Native project, validated in parallel across six wallpaper apps. Covers flag design, compatibility triage, and KPI comparison based on actual production data.
From a Rork-Built App to Monthly Break-Even at 100 Yen Subscription: Indie Numbers from May 2026
A small Rork-built utility app reached month-over-month break-even on a 100 yen subscription combined with AdMob. May 2026 numbers, decisions, and what I deliberately left out.
Rork-Specific 'expo start --offline forbidden': Four Causes in Rork's Template Config
When expo start --offline returns 'forbidden' specifically on a Rork-generated project, the cause is usually Rork template config: tsconfigPaths, an un-generated expo-router cache, native prebuild, or a lockfile mismatch. Four Rork-specific fixes; the generic Expo proxy and dependency-validation guide is covered separately.
Auditing Privacy Manifests for Rork-Generated Expo Apps — A One-Day Pre-Submission Workflow for Indie Developers
A pre-submission workflow for indie developers shipping Rork-generated Expo apps. Walks through how to enumerate every dependency, detect missing PrivacyInfo.xcprivacy files, and ship without ITMS-91053 rejections — based on twelve years of personal app development.
Three Weeks Triaging Crashlytics Velocity Alerts With Claude in Chrome
I spent three weeks letting Claude in Chrome open Firebase and triage Crashlytics Velocity Alerts for my wallpaper app. Here is what actually got easier, and what still needs human judgment.
