Finger Lie Detector is an application for Android that can detect if a person is telling the truth or lying. It is a fake detector that works on the finger pulse, the amount of sweat, and the speed of the heart rate.

The app can display a result of true or false. To use the app, you need to first set the question you want to ask and then put your finger on the scanning pad. It will then make a result of true or false based on the answer you give.

The app is great for making a joke of your friends. You can even use it as a wallpaper and widget.
