Lie Detector Simulator

The application interface is a copy of the polygraph, which further enhances the effect of its use. As in the real lie detector, the simulator recognizes insincerity using basic physical indicators: heart rate, increase in temperature and sweating, and other, less significant parameters.

It’s important to remember that the application only simulates a polygraph, and therefore you should not expect maximum accuracy of results from it. The simulator is ideal for entertaining. It can be used for mock tests with friends. You can also use the app to play tricks on your friends by secretly pressing the “True” or “False” buttons.

Questions should be asked into the microphone, and to determine the sincerity of the words you need to put your thumb on a special button on the screen. The game takes up little space in the memory of the device and doesn’t overload it with frequent updates and additions.
