Rain Alarm OSM Pro

This variant of the app is aimed at older devices. A better choice with more background map types is "Rain Alarm Pro".

This weather app and widget are able to warn you against precipitation (like rain or snow) by an alarm. You can watch what is coming by the up-to-date radar animation. Even more convenient, the supplied widgets can help you monitor the precipitation situation without any alarms.

Useful assistant for everything outdoors like cycling, biking or hiking.
