Show the In-App 'What's New' Once, Without Nagging — Version Gating and Seen State
An in-app 'What's New' screen that fires on fresh installs or shows every launch gets users annoyed. Here is a version-gated, seen-state design that delivers it exactly once to people who updated — in real Rork (Expo) code, plus a shape you reuse across multiple apps.
When a User Rewinds the Clock, Today's Card Shouldn't Break — Day Boundaries and Streak Integrity in a Daily-Content App
Daily 'card of the day' content breaks under timezone travel and manual clock changes, showing duplicates, gaps, or lost streaks. Here is a deterministic day-key and monotonic-clock design, in real Rork (Expo) code, that keeps it solid.
Your Animation Keeps Running After You Leave the Screen — Focus-Aware Battery Savings in a Rork (Expo) App
In a Rork-generated Expo app, a gradient or breathing animation can keep running after you push another screen or background the app, quietly draining the battery without ever surfacing as jank. The cause is that Reanimated's withRepeat lives on the UI thread and the navigation stack keeps screens mounted. This shows a lifecycle design — useIsFocused plus AppState — that reliably stops off-screen and background loops, with working code.
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.
Monetizing a Rork-Built App — Choosing Between Ads, Subscriptions, and Freemium
How to monetize an app built with Rork — from choosing between ads, subscriptions, freemium, and one-time purchase to the implementation details. Phased AdMob formats, treating ad-free as a single source of truth, and price anchoring, written from the indie-developer trenches.
Your Arabic Users See an Unmirrored Layout — RTL in a Rork (Expo) App and the Reload Trap
You added Arabic to a Rork-generated Expo app, but the screen never flips and the back button stays on the wrong side. The cause is that I18nManager.forceRTL requires a relaunch. This walks through detecting direction with expo-localization, applying it reliably with Updates.reloadAsync, swapping to marginStart, and mirroring only the arrows — all with working code.

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.
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.
Keep Audio Playing in the Background and Add Lock Screen Controls in a Rork App
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.
