App Development for iOS & Android

I develop mobile apps for iOS and Android from a single React Native codebase. The apps keep the look & feel of each platform.

Hasan Albari

With React Native I build apps that run on iOS and Android from a single codebase. That saves development time, and the app still uses real native UI elements, so it feels familiar on both platforms.

Where it matters I make platform-specific adjustments. Some things are simply supposed to work differently on iOS than on Android.

Because the development cycle is short, a change can often ship within a day. Handy if you want to steer the app on what users make of it.

  • Publishing to the App Store
  • Following the Human Interface Guidelines

  • Following the Material guidelines
  • Test builds via an internal track
  • Standalone builds for devices without the Play Store
