AstroClock 星空観察と天文学 アプリ 向け Android 説明
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.
