Version: 1.5.0 (see pubspec.yaml for the full version + build number).
Note
This project began as an experiment with Google Stitch and Antigravity. It is now developed in Cursor, primarily through pair-programming with Opus 4.7, to keep exploring agentic coding and automated UI design.
A Flutter weather app focused on precipitation, featuring an animated radar map and minute-by-minute nowcasting. The web build uses the Open Rain document title; iOS, Android, macOS, and web are supported targets.
- Privacy Policy:

- Live radar map with animated WMS tiles from KNMI (Netherlands Royal Meteorological Institute)
- Minute-by-minute precipitation chart synced to the radar playhead
- Rain alerts — uses Open-Meteo minutely precipitation to warn when rain is expected soon (about 20 minutes ahead) and for how long. iOS & Android: local notifications plus periodic background checks (subject to OS scheduling). Web: checks while the tab is active (browsers cannot run reliable background work like mobile).
- Current conditions — temperature, wind, UV index, humidity, feels-like
- Hourly & 14-day forecast
- Air quality index (PM2.5, PM10, ozone, NO₂)
- Severe weather alerts (via Open-Meteo)
- GPS-based location with city search fallback
- Works without an API key via anonymous KNMI access
