The spectator takes a card from a deck, and hides it so nobody can see it. Then you introduce the Card Detector app, which can decide if someone was telling the truth about their chosen card, or was lying. The spectator can hold the phone (or tablet) in their hands, you never touch the device after starting the app! The spectator says something about their card - they can tell the truth or lie ("it's a black card", "it's a number card" etc.), and then they put their finger on the screen. The Card Detector will seemingly determine if they were lying or not. After a couple of statements, you can successfully reveal the spectator's card.
This is not a real lie detector, just a magic trick with a clever method. You will find detailed instructions inside the app. Please read it before you rate the app!!!
