Mood Detector Face Test Prank is a free lifestyle app available on iPhone. It is a fake photo scanner simulator app that allows users to prank their family and friends. Developed by Tim Denyer, this app is from the same makers as Naughty or Nice Photo Scanner, Lie Detector Face Test, and Hot O Meter Free.

The app works by allowing users to choose an existing photo from their album or take a new photo. Once the photo is selected, users can press start and the app will scan the photo. After the scanning process is completed, the app displays an emoji that reflects the detected mood and speaks the result.

Please note that Mood Detector Face Test Prank is for entertainment purposes only. Despite its realistic appearance, the app does not actually have photo scanning capabilities and is intended to be a joke app.
