AstroClock is an astronomically correct 24-hour clock.Instead of an ordinary dial, it shows the sky exactly as it currently stands above your location: the Sun travels around the dial once per day as the hour hand, and the entire starry sky turns along with it – just as it really does overhead.
Features:
* The Sun as the hour hand of a true 24-hour clock
* The co-rotating starry sky with constellations for your location
* Realistic Moon phase and the visible planets
* Compass / azimuth scale along the horizon
* Sunrise, sunset, moonrise and moonset as markers
* Location set by place name or coordinates
* Usable as a live wallpaper
* Home screen widget in a clear compact layout
Privacy:
AstroClock collects no data and contains no ads and no trackers. The app requests no location permission – you enter the location yourself. The only external connection happens when you search for a place by name; the search term is then sent to the free OpenStreetMap Nominatim service to turn it into coordinates. If you enter coordinates directly, no network access takes place at all.
WhatsNew:
First release of AstroClock.
Anti-Features: TetheredNet(This app is bound to a certain network service):
⇒ Rely on openstreetmap.org
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
