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.'

Dinsun Review

Dinsun here. I don't even know why I'm reviewing this. It’s not a game. It’s a trick app from the early 2010s that somehow still exists. You press a button, it makes a sound, and tells you someone is lying. It's built solely to serve you ads every three seconds. If you're over the age of eight, this has zero value. If you're under eight, you'll still be bored in two minutes. Waste of space.

    No, this app is for entertainment and prank purposes only. Mobile phones do not have the hardware to perform real polygraph tests.
