Short answer
A2Z Global built FitPak's fitness app for iOS and Android from one React Native codebase. It shipped on schedule and crash-free, holds a 4.8-star store rating, and members use it daily.
/Scope
What we built
- iOS and Android from one codebase, so features land on both at once.
- Authentication, notifications and sync without running servers.
- Daily-use flows designed to be fast, because a fitness app is opened in a hurry.
- Store submission handled, including listings and review requirements.
