We write iOS and Android applications with React Native, dropping to native modules where performance requires it. Store submission, release management and crash reporting are part of the work.
iOS and Android from one codebase.
For camera access, biometrics, background location and similar platform-specific needs we write native modules without hesitation. The user should never be able to tell which framework the app was built with.
We know Apple's and Google's review rules. Privacy declarations, permission justifications and store assets are prepared in full, and if a submission is rejected we manage the revision.
