One codebase, both app stores

We build iOS and Android apps with React Native - one codebase for both platforms, shared with your web app where it makes sense, taken all the way through App Store and Google Play release.

Is it a fit?

Who we build this for

A good fit if you have

  • Both iOS and Android without two separate teams
  • A React web product adding a mobile app
  • An app that needs a team to take over and keep shipping

Probably not for

  • Graphics-heavy games - a game engine is the better tool
