Thermal Camera Photo Filter Simulator by Just4Fun Tools is a prank tool that simulates a thermal camera effect. It should be noted that the app does not have the capability to change your phone into a thermal camera device or detect an object's temperature. The app is available for free on Android devices.

The app provides a thermographic camera filter that processes the video stream from your built-in camera in real-time. It uses a high-tech algorithm for pixel luminance detection and color gradient mapping to generate a view that closely resembles the vision from a real thermographic camera. The app offers three gradient map color schemes, three pixel lumination detector algorithms, and a live thermal power amplifier. It is an ideal tool for making jokes with your friends, and it also has an instant button for taking stunning photos that can be saved in your photo album.
