Problem
Manual water testing is slow and inconsistent. It does not give continuous readings. Existing tools often lack real-time sync or need a complicated setup, and they offer little long-term analytics.
What I built
- A cross-platform app in Flutter for Android and iOS.
- Bluetooth connection to ESP NodeMCU sensor devices for live readings.
- Firebase Realtime Database for instant sync and storage.
- Analytics for long-term tracking.
