Used it for a while, but unfortunately, the data at Openweathermap was just way off for my location (Germany). Switched to FOSS Weather (https://f-droid.org/en/packages/de.baumann.weather/ https://f-droid.org/en/packages/de.baumann.weather/), which is a wrapper around wetterdienst.de. Unfortunately, this app is no longer maintained, but it still works perfectly fine.
