Use this app to detect if someone is lying. The subject must hold the phone and the app measures the shakes in their hand. If their hand starts shaking, the line will start getting larger and turn red. This app is very sensitive to even the slightest hand shakes. If a person's hand starts shaking more, it is proven, that they are much more likely to be lying. And, if someone is lying, then their hand is more likely than not to be shaking more than average. http://www.8d8apps.com/
