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.
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.

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.
A Wallpaper App's Real Work Starts After Launch — Content, Retention, and Revenue Notes from Running One on Rork
A wallpaper app is decided less by its launch and more by how you tend it afterward.

Stop Burning Your One Push-Permission Shot on App Launch — Pre-Prompt Priming for Rork Apps
If your Rork (Expo) app fires the OS push-permission dialog at launch, every 'Don't Allow' tap closes that channel forever — iOS won't let you ask again. Here's how a self-built pre-permission screen lifts your opt-in rate, with the Expo code to do it.
Win Back Lapsed Users with App Store In-App Events — Deep Link Implementation for Rork (Expo) Apps
An implementation memo on bringing lapsed users back to a Rork (Expo) app using App Store in-app events. Covers event card design, universal link routing, and measurement, from a solo developer's operational view.
Choose Native Features by Retention Impact, Not by Checklist
Rork Max can generate widgets, Live Activities, and Core ML alike. But 'can build' and 'should build' are different things. Here is how to decide native-feature adoption by its effect on retention.
You Only Get to Ask Once — Implementing a Notification Soft-Ask in Your Rork App to Lift Opt-In
On iOS, once a user denies the notification prompt you can never show it again. In a Rork (Expo) app, instead of firing the system prompt on launch, we add our own soft-ask screen and only request permission once the value has landed. Built with expo-notifications, covering Android 13 POST_NOTIFICATIONS, a recovery path after denial, and opt-in measurement.
