Simple application which displays the air temperature and other weather conditions in the Android notification bar. The air temperature is always visible like a system clock.
The current location can be detected automatically or be entered manually.
The weather is requested from http://openweathermap.org.
This is the core application. To display the current temperature in different colors or styles, install skins. Skins can be installed on SD card.
