Inbuilt face scanner and fingerprint scanner both are available in this app for truth or lie detection. The app also speaks in robotic voice. Also, you can see when using the app that if you remove your face, the scanner stops and resumes only when you bring face back. But this app is actually a prank. Though if you want to use face detection and record it's truth or lie detection, you can do it by unlocking that feature using in-app purchase. That recording is completely private. NOTE - PLEASE READ THE INSTRUCTIONS ON FIRST START CAREFULLY AS THEY WON'T APPEAR AGAIN DUE TO THE NATURE OF PRANK. MAINLY THAT IS PRESSING LEFT OF START DETECTION BUTTON WILL GIVE TRUTH AND PRESSING RIGHT WILL GIVE LIE.
