About Rain
Rain is an open-source weather application built with Flutter. It shows current conditions, hourly and 12-day forecasts, and air quality, with saved cities and a map view. The directory lists it as an Android app, and the repository also includes build targets for iOS, Linux, macOS, Windows, and web. The GitHub page is a source repository. Prebuilt APK and other builds are available from the project's Releases page.
Weather, air quality, geocoding, and map tiles come from external services: Open-Meteo and OpenStreetMap. The project describes these as free APIs that require no key. Some features depend on these services, and the source does not describe how data is handled beyond that. Building from source requires Flutter 3.44 or later and Dart 3.12 or later.
