My mobile app, fastdials, is live and functioning, but it is still missing two key features: paid subscriptions on iOS and rich push notifications on both iOS and Android.The app is build on React native, Expo and node.js (backend). 1) In-App Purchase I need StoreKit-based integration for a recurring Subscription product on iOS. The purchase flow must handle new subscriptions, renewals, cancellations, error states and graceful recovery of interrupted transactions, all while respecting Apple guidelines. Once the transaction is verified, the user’s entitlements should be stored or refreshed so that the rest of the app can unlock the premium tier immediately. 2) Cross-platform push notifications A backend server is already in place; what’s left is wiring the mobile clients to it. The app has to display the following kinds of notifications: • Promotional messages • Transactional alerts • User activity updates Tokens need to be registered with the server, notifications received in foreground/background, and tap actions routed to the correct screen. Badge count, sound, and channel/category handling should behave natively on each platform. Deliverables – Updated iOS project with fully tested subscription flow and sandbox test cases – Updated iOS and Android projects with push implementation connected to my existing server endpoints – Brief setup document so I can reproduce certificates, keys, or provisioning steps for future releases If you have recent experience shipping subscription-based IAP and push on both platforms, I’d love to see how you can wrap this up quickly and cleanly.
