What's included
What you get.
Building two separate apps doubles the cost and the time to market. With React Native or Flutter we share most of the code between iOS and Android, while still using native modules wherever a feature needs them, so you ship faster and maintain one product instead of two.
iOS & Android apps
One codebase that runs natively on iPhone, iPad and Android phones and tablets.
Native features
Camera, maps, payments, biometrics, push notifications and offline storage.
Web from the same code
Optionally share screens and logic with a web or PWA version of your app.
Store launches
App Store and Google Play releases, plus over-the-air updates for quick fixes.
