This application is a simple tool intended to help a person develop the memory skills needed to remember the cards that have been played. This is not a card counting tool to be used during a real game, and it doesn't calculate any odds or show any playing strategies.
It's a very simple application: Cards are displayed one at a time, and you deal them out one at a time by touching an on-screen button, swiping your finger on the screen, or flipping your device to the side and back. At any time you can touch the Info button on the lower right to reveal the number of each rank that's been displayed, as well as some other useful and easily calculated numbers. Touching Done button returns you to the last card shown. Touching the Shuffle button starts a new deck. That's it.
(Please do not use the App Store reviews to let me know should you have problems or suggestions. Emails will get my attention a lot faster. )
