I just launched Fight Clock, an app for round timing of boxing, MMA and Muay Thai – 3 of my hobbies, when lack of injuries permits. It’s built using Expo / React Native / TypeScript. So the same code base will work seamlessly on web, Android and iOS.

But the USP of Expo / React Native is actually the ability to push small fixes and updates ‘OTA’, without requiring a new mobile release. This way, fixes can be delivered to users transparently in minutes, not days.
