"It is a simple, no-frills, app that can be used to reveal up to three lines of text on your iPhone when the spectator calls you from their own phone.
Recommended!"
- Carl Andrews, Vanish Magazine
The effect:
The magician begins the trick by calling the spectators phone. He points out that the spectators number is unknown by the phone because they have never even met. The magician hangs up and immediately places the phone in another spectators hands for safekeeping. The spectator freely chooses a card and returns it to the deck. The magician now asks the spectator to call him back, directing the attention back to the untouched phone. The spectator makes the call. Instead of displaying the unknown phone number, the phone now displays the spectators name and the chosen card!
