Pulse
Pulse needed a fitness app that felt fast enough to check mid-workout, syncing activity across iOS and Android without standing up a second engineering team.
Challenge
Their original app was iOS-only and built natively — reaching the Android users behind half their waitlist signups would have meant hiring and running a second platform team from scratch.
Solution
We rebuilt Pulse in React Native from a single shared codebase, added offline-first workout logging that syncs the moment a connection returns, and shipped to both stores in the same release cycle.

“We assumed going cross-platform would mean compromising on feel. It didn't — our Android users can't tell it wasn't built natively for them, and we shipped in a fraction of the time a second native app would have taken.”
