Building a Dive Log App with React Native

Most existing dive log apps are either clunky desktop relics or overpriced subscription services. Building your own is more approachable than you might think.

Offline-First Architecture

Dive boats rarely have reliable internet. Your app must store logs locally using SQLite or WatermelonDB, then sync when connectivity returns.

BLE Integration

Modern dive computers broadcast dive profiles over Bluetooth Low Energy. React Native's BLE libraries make reading this data straightforward on both iOS and Android.
