Vision vs dnCalc

IMPORTANT: That you really can use the app, you have to make an in-app purchase. Without the in-app purchase, you will have only some basic functionality to verify, that the app does really what you expect. A face-up spread of playing cards can be captured via the video-stream from the back camera of the iPhone. The order of the playing cards will be detected and can be displayed. All missing cards can be displayed too. All regular Poker-Playing cards (Bicycle, Phoenix) are detected. Also the new Phoenix Large Index Deck is supported. Important: Jokers are NOT detected! The detection and analysis works very fast (faster than 1 second). The app has a variety of different settings. To unlock the whole functionality, you can purchase the monthly subscription "Full Access". With this subscription you unlock (for the time periode of the subscription) all features of Vision. In addition to that, it also unlocks (for the same time periode) all in-app purchases of the companion app Vision:Tricks.

Imagine... You are enjoying a lunch with friends and you suggest to perform a strange mathematical "experience". You ask for several volunteers to think of a special number, a birthday, the age of their best friend... You then ask them to multiply these numbers together, without you being able to see anything, then multiply the result by a special number that you previously wrote on a piece of paper, before the demonstration begins. Your friends give you orally the final result of these operations. You close your eyes and after a few seconds you reveal in the right order, the secret numbers of your friends! dnCalc will allow you to easily produce this little miracle that you can adapt according to your wishes and to he context. Your friends or colleagues will be asking what magical mathematical operation you mentally do to "extract" their numbers. Guaranteed to impress! • Very easy to do. A PDF document explains in details the procedure (which you can adapt). • Nothing to memorize. • Up to 5 people can be involved in the demonstration. • The spectators manipulate the calculator, you do not touch anything. • You can do this demonstration with your eyes closed. • No need for internet connection. • The trick is absolutely undetectable, nothing to find. • The effect is reproducible several times in a row. Many other cool features : • Force any number you need. • Compute and peek the age of your volunteer. • Compute and peek his zodiac signs (classic or Chinese). • Compute and peek his birth day of week. • Build your own forcing/peeking formulas! *** IMPORTANT *** If you have questions, do not ask them in the app's reviews, in order to preserve the secret.
