ISO - Kerstein & Qualter

I have several of his apps and oh boy they are GREAT!!!!

With ISO, Marc has created another reliable and versatile magic app that allows for mind blowing performances using a borrowed phone of a spectator. (Nothing is installed on their phone). The app runs flawlessly; video and written instructions are provided within the app. As always, Marc continually updates his apps, keeping them working as software updates and adding incredible features. Excellent support and customer service.

Marc Kerstein is by far one of the best ap developers for magic hands down. His aps personally have always been my go to when I’m not carrying anything. ISO is amazing and one of Marc’s top aps in my opinion. Easy to maneuver and the tutorials are very easy to watch with many ideas and effects you can do. This is a must have for any magician

Powerful concept flawlessly executed.
