This app let’s you add a small Weather Tile to your Quick Settings Bar on Android Nougat (7.0)!
The text shows you the current temperature while a small icon displays one of 12 different weather conditions.
Clicking the tile will update the weather data. When clicked, a small Forecast for the next three days opens.
You can configure the tile by tapping it and change, whether you want to use Celsius or Fahrenheit, if there should be a small weather description and how often it should refresh automatically. You can also choose one of five background colors for the forecast window.
