Orloj is a feature-rich astronomical clock app developed by MadrSoft. Available on the Android platform, this free app offers a comprehensive display of various time elements and celestial information.

The clock showcases several time measurements, including 24-hour local solar time and German time. Additionally, it presents Babylon's uneven hours calculated from sunrise, as well as the Old Bohemian time calculated from sunset. Users can also observe the position of the sun and moon on the zodiac and the ecliptic, along with the current moon phase.

Orloj also provides valuable information such as the sunrise and sunset times for both the Sun and Moon, as well as astronomical twilight. Moreover, the app includes a gold star that indicates star time or sidereal time.

Designed to replicate the famous astronomical clock in Prague's Old Town Square, Orloj accurately adjusts to the local solar time of the aforementioned location. Whether used as an app or a widget, Orloj offers a visually appealing and informative experience for astronomy enthusiasts and those interested in tracking celestial phenomena.
