Cross-Platform App Development
One codebase for iPhone, Android and the web.
We build cross-platform apps with React Native on a modern toolchain, with native Swift and Kotlin code where it counts. One team, one codebase, every platform kept in step.
Every platform, kept in step.
Ship to iPhone, Android and the web together, and keep them moving fast after launch.
One release. Every platform.
A fix ships to iPhone, Android and the web together. Many fixes and content changes reach users without waiting for store review.

React Native app development FAQ
Is React Native as good as native?
For most apps, yes. React Native renders real native components, and we write Swift or Kotlin where a feature needs it. For graphics-heavy or highly specialised apps we may recommend fully native.
Can you update a React Native app without app store review?
Many updates, such as fixes and content changes, can go straight to users. Changes to native code still go through App Store and Google Play review.
Can one codebase include a web app?
Yes. Much of the code can be shared with a web version, so features stay in step across every platform.
Will the app feel native?
Yes. React Native uses real platform components, and we follow iOS and Android design conventions so each version feels at home.
Can you move our existing apps to React Native?
Yes. We can migrate screen by screen, so the app keeps working while it moves to one shared codebase.
How much does a cross-platform app cost?
Price follows scope. A proof-of-value build starts from £15k, and a full design spec with a dedicated team runs up to £140k. Read more in custom software development costs.
