The app comes with the Earth and Mars clocks free of charge, and additional planet clocks can be purchased through the app or the App Store.

Did you ever want to know the time on Saturn?
The simple Solar System Clock can tell the time on any planet or dwarf planet, and the Sun in relation to Earth time. Calculated from the starting date of the Gregorian calendar, the app displays seconds, minutes, hours, days and years for each object based on orbit and rotation data. The time is given in both analog and digital formats and can be stopped and restarted for easy viewing, while keeping to the accurate localised time. A single analog clock face for all planets and dwarf planets is also included, and can be split into two clocks for main planets and dwarf planets. A widget form of the Earth and Mars clocks is also provided for circular widget slots on Apple Watch.

The main clock can also be projected as functional wall art.
