Sun & Moon Tracker is a lifestyle application developed by PYOPYO Studio, available for free on the Android platform. As the name suggests, it is a 3D virtualization app that allows users to track the position of the sun and moon at any time of the day.

The app provides a 3D compass ball that displays the position of the sun and moon, along with their set and rise time. It also features moon phase tracking, and a unique time machine that allows users to adjust the time and date. Additionally, the app provides a manual calibration compass when the auto-calibration does not work well. However, it is important to remove the metal case or magnetic cover to avoid interference and get accurate orientation.

Overall, Sun & Moon Tracker is a useful application for those who want to keep track of the sun and moon position in real-time. With its 3D virtualization feature and time machine, users can easily plan their activities and schedule their day accordingly.
