Notion Tech builds iPhone and Android apps with React Native and Expo. One team and one codebase deliver native apps for both platforms. The Rostery worker app, built this way, is live on the App Store and Google Play.

App Store and Google Play review handled.
React Native renders real native components, so apps feel right on each platform, while most of the code is shared. Expo adds a reliable build pipeline and over-the-air updates, which let us ship fixes without waiting for a new store review.
The Rostery worker app handles GPS clock-in, background location, trip capture, offline notes and push notifications on a wide range of phones. We have been through App Store and Google Play review many times, including the privacy and location questions that often delay launches.

No. One team builds both from one codebase, which lowers cost and keeps features in step.
Yes. We store data on the device and sync when the connection returns.
Small fixes can ship over the air through Expo. Larger changes go through store review, which we handle.
