The Lie Detector Simulator by Ketur Vribs is a fun and harmless prank app that simulates a fingerprint scanner to detect lies. It's perfect for pranking friends, kids, and others. The app allows you to preset answers in the settings menu, and then ask questions while your friends place their finger on the fingerprint scanner. The app then displays the preset answers, which can be either truth or lie.

In addition to the lie detector simulation, the app also includes other funny features such as Hair Clipper, Funny Sound, and Hilarious Sound. Hair Clipper is a realistic prank app that simulates a real hair trimmer or clipper. Funny Sound includes popular comedy sound effects and audio memes, such as Air horn, Laugh, Claps, Fart, Whistle, Punch, OMG, Police, and Remote. Fortepiano allows you to play piano notes, while Hilarious Sound includes funny sounds like Bomb, Cat, Fart, Dog, Rate, Door, Broke, and Ghost.

However, it is important to note that this app is just for fun and is not a real-life lie detector. The truth or lie is not determined by your fingerprint or device. It's just a joke or simulation app.
