Thermal Camera FX: SimPrank is a free Android app developed by webcamfx. It is a shader effect app that simulates a thermal vision camera or Infrared heat sensing camera. The app allows you to save photos from the camera, record videos, and apply real-time effects on video, pictures, and device image. It supports camera flash, front camera, and hardware camera button. The effect sensitivity can be adjusted on the fly, and the app can be installed on the SD card. The app offers multiple thermal camera profiles and effect sets.

It is important to note that Thermal Camera FX: SimPrank is not a real thermal vision camera, and it does not detect any infra-red or have any short of heat sensing. It is solely a camera effect app that generates cool photos and videos with effects. The app can simulate thermal vision, but it cannot see in the infrared spectrum using your Android camera. Saved images and videos are stored inside the camera folder "DCIM/ILThermaCamera". The app has been tested on various devices, including Nexus 6p, Samsung Galaxy A5, Sony Xperia M4Aqua, Sony Xperia E3, Sony Xperia M, Htc desire 820s, and Asus PhonePad7.
