Sun Time

Align your biorhythm with the sun

When the sun is at the highest point, it's noon, so it's 12:00 p.m., right? That's the way things should be. This app shows you the solar time at your location. 12:00 p.m. is natural solar noon, and the sun is at its highest point. 12:00 a.m. is the natural solar midnight, and the sun is at its lowest point. See solar time in comparison to your zone time in the main app, and see the solar time in a nifty widget. You can use this app to wake up at a solar time of your choosing.

Packages

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
