FPS Monitor is a utility application designed for Android devices that provides real-time tracking of frames per second (FPS) during gaming. It caters to power users who wish to keep a close eye on their game's performance metrics. The application features a floating FPS overlay that allows users to monitor their FPS while engaged in gameplay, ensuring they have precise data at their fingertips. Additionally, it provides real-time GPU FPS data, allowing for accurate performance assessments directly from the device’s graphics processing unit.

Customization is a key aspect of FPS Monitor, as users can adjust the overlay's size, position, and color to fit their gaming setup. Furthermore, the app allows users to change the refresh frequency of the FPS data, enabling smoother tracking according to personal preferences. It's important to note that the application requires Shizuku to function effectively, and it operates independently without claiming ownership of any monitored games.
