Unconvinced

Frankly this app has not convinced me. Have therefore changed yet again to Wetter.com. After 2 days was my (already minimal) Internet volume empty. For some reason, the app has dispatched within 2 days just 200MB, which seems to me too much when you consider that it needs to retrieve only the weather information. The design of widgets also like not really me and the fact that I can not adjust how often it should update the weather (it's on every 30 minutes. Set) has, let me uninstall the app after a week.
