A loyalty app rebuilt for iOS and Android without losing a single customer
We replaced a loyalty platform’s native iOS app with a single Flutter app for iOS and Android, keeping the backend, accounts and user data.
The challenge
Reaching Android too without maintaining two codebases, and without forcing existing users to sign up again.
What we built
- QR loyalty card, also as a widget, with points, rewards and coupons
- Store showcase and search, chat with stores and push notifications
- Bookings, cart, orders and payments with Stripe and PayPal
- Sign-in with email, Apple, Facebook or as a guest
- Offline support and three languages
- Automatic migration from the old app, with no new login
Security
Keys kept out of the source code and tokens stored in the device’s secure storage.
Numbers from the project
