Lunar phase graphical representation. Sunlight terminator which shows which which part of the Earth is illuminated by the Sun. It does it based on the hour and declination (calculated from the date). Not all variables are recalculated every minute, to save energy. For instance, the Moon phase and the Sun declination are recalculated only once a day.
It also displays an analog watch with symbols for sound, vibration, "move", alarms, connection to the phone, presence of notifications, memory usage, remaining battery level. Displays the date, miles / kilometers. The bars represent the history of steps during the last week, the steps today, and the last bar represents the steps goal. Next to it, the goal in numbers (vertical number).

The app is open source. If you are a programmer, feel free to download it, modify it, fix bugs, add functionalities, or simply test it on different watches and upload it yourself. Don't forget to share your code as I did.
