SunPath is a free Android app developed by Carr devs that uses your smartphone camera to display the sun's path in the sky at any given moment. By pointing your camera towards the sky, the app shows the movement of the sun with impressive accuracy. The app is designed to provide users with a range of useful features, including the shortest and longest days of the year, and a date picker that enables users to see the complete coverage of the sun throughout the year.

SunPath is a highly intuitive and user-friendly app that provides a unique way to track the sun's path. Its interface is straightforward and easy to navigate, making it accessible to a wide range of users. Although the app is designed for smartphones, it may work on tablets as well, but it's known to be inconsistent on numerous Android tablets due to technical reasons. Overall, SunPath is an excellent app for anyone interested in tracking the sun's movement and understanding its patterns.
