“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.

Amalgam comprises of multiple effects, all within one app. All effects are chosen to be powerful, yet easy to perform. And each effect requires nothing more than just your phone. Amalgam includes instructions as well as various customisation settings. It even includes a community section for user-submitted tips and routines. AMALGAM INCLUDES: * Streets * Streets is finally back! John Archer has given his exclusive permission for this remake of his popular Streets app, which now incorporates new features including a modernised real map and a new "gyro crib". - Divine where in the world your spectator is thinking of! - A book test with no memory work required. - A new "legitimate mode" which supports all languages. * TimedOut * A customisable prediction effect that's all in your spectator's hands. Predict a number, dice roll, ESP symbol, star sign or more. - Prediction can be an image in your Photos or perhaps a drawing. - After making your prediction, you do not touch the phone again. - No Internet or Bluetooth required: nothing is sent to or from the device. - Your spectator checks the prediction themselves: the phone remains in their hands! - No voice recognition! - Perfect for pairing with other electronic mentalism effects: reveal a photo from two days ago of you predicting their dice roll, which even they don't know yet! * Watch * A revelation of a freely chosen time. Your spectator zooms in to a wristwatch in a photograph to find it's set to the time they just named. - Customisable: use your own photo. - Any time can be named to the minute. - Novel method: no voice recognition or unjustified inputs. * Word Search * Seemingly demonstrate superhuman memory abilities with this word search game from Harry De Cruz. Although you only look at the word search for a couple of seconds, you can reveal the positions and directions of all words hiding within. - Method keeps memory work to a minimum: if you know the alphabet, you can perform this effect. - No need to secretly obtain information during the effect. - Phone remains in the spectator's hands. * Inertia * Force text, photos and videos on any website, without hiding the screen from the spectator. Inertia works great as a prediction effect, or combined with your favourite revelation. - Predict a word on any website. - Force photos or videos on Instagram. - Reveal you predicted a selected Tweet, movie or Instagram post. * OneStopShop * This fully customisable effect allows you to force a product of your choosing from an online store. - Novel input method combining old and new mechanics. - Multiple built-in presets, or create your own. - Force multiple playing card back designs, thanks to Theory11, Daniel Madison and Patrick Kun. - Built-in clothing preset is perfect to combine with physical effects, such as Dresscode by Calen Morelli. * ChoiceMail * Your spectator's selection is impossibly revealed when listening to a received audio message. - Input mechanism allows you to secretly code the reveal in performance. - Novel input peek system is hidden in plain sight. - HUGE thanks go to AGT winner Shin Lim, who has recorded the built-in presets! - Also fully customisable with custom presets. * Amped * Using a combination of screenshots, Amped lets you demonstrate your apparent superhuman powers over technology. - Included settings allow for multiple customisation options. - Ends clean - device can be fully inspected at the end of the performance. - Combine with a Charge Card (sold separately) for a physical effect. MORE INFO: Each effect in Amalgam includes detailed in-app instructions and settings. The included effects are for entertainment purposes only, designed for professional performers.
