“There are very few effects that transcend ‘magic trick’. ’The Stranger' is one of those effects." -David Regal, "Genii Magazine" “The Stranger” offers unlimited scenarios: A playing card is chosen, a word is thought of from a Book Test, the numbers from someone’s address are named, an envelope is freely selected, or the name of someone’s loved one is offered…and then, a random stranger is called. The audience has a conversation with the stranger and the stranger reveals the information. This is an impossible moment. It leaves the audience with a feeling they cannot explain and they erupt in applause! Not out of a desire to be kind, rather as an uncontrollable, visceral reaction. And it happens every time. With this purchase, you can have a playing card—any card, using no force of any kind—revealed by a stranger. Other effects can be unlocked to allow a number or a word revealed, read an NFC tag, or to simply allow the audience member to speak and have key details revealed by the stranger on the other end of the call without the performer saying a word. “It crushed! One guy jumped out of his seat and ran out of the theater!” —Larry Wilmore “So clever... the method alone opens up SO many possibilities” —Danny Garcia "It may just be the most fantastic five minutes of entertainment possible with a cell phone!” —Jim Steinmeyer “This is one of the strongest and most well put together phone app effects I've ever seen!” —Tony Clark “This brilliantly thought-out routine defies explanation.” —Mike Caveney “Jonathan has put a lot of work into this versatile app to make it an incredibly useful approach to the modern day Mr. Wizard effect… and much more!” — Marc Kerstein "I am having a blast with ‘The Stranger.’ A perfect, offbeat trick that I pull out when I want to send them over the edge.” —Paul Gertner “You did it! This is definitely the best 'Call a Stranger' idea ever! For the working pro to the beginner. This is a real winner!” —Dan Harlan “When I watched Jonathan Levit perform ’The Stranger,' he received the largest explosive reaction I've ever heard inside the Chicago Magic Lounge.” —Danny Orleans “Jonathan has thought of everything. Do yourself a huge favor, download 'The Stranger' today!” —Carl Andrews, "Vanish Magazine" INTERNATIONAL GLOBALIZATION: Support for International regions and languages include the following: Phone Number Display: When dialing a phone number within or to a country, the proper phone number format will display on screen.
