About AstroClock

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.
