- Highlight function for quick verification
- Offline-first with no data collection
Lessons Learned
For a tool used under time pressure at a teller window, every tap had to count. Expo and React Native made it straightforward to iterate on the UI while keeping calculations instant and the experience smooth on a range of Android devices.
