Perform amazing "Which Hand" and "Free Will" routines using your iPhone and AirPods.* This app harnesses the high-end technology inside of the AirPod to secretly cue the magician when it is in motion. Keep your iPhone in your pocket to feel a vibration, or peek the information in plain sight. And at the end of the routine, you can open your Notes app to prove you had perfectly predicted the outcome... every time. This classic mentalism plot has never been more practical—you do not need to carry any extra gadgets to perform. There is no touching or scanning, and you can retrieve the information from 30-60 feet away. These electronic methods have long been inaccessible to the casual magician. Echolocation is here to help. *This app functions with AirPods Pro, AirPods (3rd generation), and beyond.
