Lie Dectector Prank in IOS

Our Expert Score

45/100

Let's be clear: this is a prank app, not a scientific instrument. As a tool for messing with your friends, it’s functional and has some fun visual flair. The app uses 'fingerprint scanning' (simulated by holding your thumb on the screen) to determine if someone is lying. The trick, of course, is that the user can secretely control the result using hidden buttons or volume keys.

It’s a novelty that wears off after about five minutes. The graphics are decent, attempting to look like a high-tech polygraph, and the sound effects add to the tension. However, it’s plagued by ads and doesn't offer much beyond the core gimmick. If you're looking for a quick laugh at a party, it's fine, but don't expect any depth or actual 'gameplay.'
