The project
Street Parking is a fitness app with new daily workouts, 60+ training programs, expert coaches and a worldwide community. Its app was built on NativeScript.
Moving it to React Native and Expo meant rebuilding a live app that tens of thousands of paying members rely on. While I was at Launchpoint Dev, I led that migration and carried most of the rebuild myself.
What I did
NativeScript to React Native and Expo. Led the ground-up migration of the app to React Native and Expo, doing most of the rebuild myself.
Custom subscription paywall. Built the paywall from scratch, with no RevenueCat, handling Stripe, Apple Pay and Google Play billing for 30k+ active subscribers.
How the migration went
The whole project took about two to three months from start to finish, in three phases.
Rebuild (2–3 weeks). Moved the app from NativeScript onto React Native and Expo.
Clean-up (about 2 weeks). Worked through the rough edges the rebuild left behind.
Polish (1–2 weeks). Finished with better animations and a round of improvements across the app.
The results
A better-feeling app. The biggest win was the overall feel of the app for members.
Faster feature work. The new codebase made it practical to take on more of the client's feature requests.
Over-the-air updates. Expo let the team ship fixes and updates straight to users without waiting on a full app store release.
