This stylish transparent Clock app and home screen widget shows the current hour with day and night indicated using shading. By combining nature with technology you can easily view daylight hours on a range of 24 hour analog clock faces.
The app has a built-in home page widget, just press the + button at the bottom of the Android home screen and select the Daylight Clock widget (available in small, medium, and large sizes). See the times for sunrise and sunset right on your phone's home screen.
Note: To save battery power, Daylight Clock does not turn on GPS. Instead it relies on your most recent GPS or Cell fix to compute sunrise and sunset times.
