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.
