When only notifications fail in Expo Go: three checks, then the shortest move to a development build
If push notifications never reach your Android device in Expo Go, check these three things before touching device settings, then move to a development build with the fewest steps. Also: how to spot what else Expo Go can't test.
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.
Building Fortune & Manifestation Apps with Rork — Daily Delivery Design That Survives Day Three
Fortune apps lose most users in three days. A Rork design for daily delivery, push timing, and widgets that turns the niche into a habit.
Adding a Notification Service Extension to a Rork App — Rich Push, Encrypted Payloads, and Dynamic Rewriting
Wiring a Notification Service Extension into a Rork-built iOS app — image attachments, end-to-end encrypted payloads, and dynamic APNs payload rewriting — with working Swift code and the production pitfalls that bit me along the way.
We Stopped Sending Push Notifications and Churn Dropped — Building an AI-Powered Churn Prediction System in Rork Max
Learn how to build a churn prediction system in Rork Max using Supabase Edge Functions, Claude API for personalized messages, and OneSignal for targeted delivery. Full implementation with code.
Retention and LTV for Rork Apps — Separating the Two Numbers I Kept Confusing
Install retention and subscription retention use different denominators. Starting from the LTV miscalculation that came from mixing them, this walks through reading Day1/Day7/Day30 correctly, costing in generation credits, and catching churn signals early — from an indie developer's desk.
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.
A Custom Screen Appears When You Long-Press a Notification in a Rork Max App — Implementing a Notification Content Extension
How to add a Notification Content Extension to a Swift app generated by Rork Max so a custom UI is drawn only when the notification expands. Covers the split with the Service Extension, updating the in-notification UI from a button, sharing state via an App Group, and the order to check when nothing shows — all with working code.
Keeping Expo Push Tokens from Slipping Through the Cracks in Production
After adding re-engagement push to a Rork-generated Expo app, the delivered count came in well below the active install count. The cause was missed token updates and stale tokens left to pile up. Here is the lifecycle I settled on, with code: registration, refresh, server storage, and pruning.
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.
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.
Push Notifications Not Working on Android 13+ in Rork Apps — Adding POST_NOTIFICATIONS Permission
Push notifications silently failing on Android 13+? The culprit is usually a missing POST_NOTIFICATIONS permission. Here's how to add it to your Rork-generated app.
