About ISO - Kerstein & Qualter
“Marc's apps are unbelievable.” —David Blaine ISO is a digital solution which enables many analogue effects. ISO lets you perform miracles using a borrowed phone. *** You can use ISO for: - Bill to impossible location - A book test with ANY printed text (a restaurant menu, a borrowed book, a magazine, etc) - Pegasus page - Playing card forces - Stacked deck effects ...and so much more! For example... imagine: - You ask your spectator to borrow a bill, which they place on the table in front of them. - Using THEIR phone, you openly take a photo of the bill to verify later. - You crumple the bill into a ball in your hand, and have your spectator hold your wrist. - You slowly open your hand to show that the bill has now VANISHED! - The spectator then checks under their bag to find the bill! - They check the serial number… it MATCHES the photo! It’s the SAME bill! * Your phone is NEVER in play! ISO only uses the spectator’s phone during the effect, meaning your phone is never seen. * Carefully justified in every way All stages of ISO’s possible effects and routines have been carefully thought through and are justified at each step. * Works in ANY language ISO is performable in any language. No text is visible during the effect, and so ISO can be used in any country or region. * Introducing Serial AR A new way to use ISO in collaboration with William O'Connell. ISO is now even easier to perform, removing the need to take a photo in advance! (Serial AR requires a one-off, optional in-app purchase. It currently works with GBP, USD, EUR, CAD, HKD, CHF, KRW, BRL, RUP, INR bills, with more being added over time.) * Multiple pairing methods Includes an adaptive peek screen, plus optional printable pairing stickers and NFC tag support. * Fully customisable The many included settings, features and modes available let you use ISO for many different effects. * WikiTest pairing integration Performing ISO can leave your spectator paired and ready to perform WikiTest at the conclusion of ISO’s effect. * VERY easy to perform * NO accomplice used * NO memory work needed ISO is for entertainment purposes only. Please get in touch to discuss video/audio/TV/internet broadcasting of any description of this effect.
