Grandmaster of Memory

Need help becoming a grandmaster of memory? Well here is the application for it. If you don't know what it is, here are the requirements:
-Memorize 1000 digits in an hour
-Memorize a 52 playing cards in 2 minutes
-Memorize 10 decks of cards in an hour
This app will help you take care of the numbers part. This is not the final revision. Upcoming functionalities include random cards, possibly more animations, tests to see if you have memorized, new icon, and more. Comment to suggest more functions.
If you don't know much about memorizing, visit pmemory.com, or look up visual mnemonics. I can assure you these feats are possible and can easily be accomplished with the proper training.
Expect Updates. I have a lot of school-work, but I will work on this with whatever free-time I have.
Press the back button to exit the switching numbers. The intent of this application was to work on associating pictures to these numbers. It's good practice for those who know P-memory.
Please comment and review. It's very helpful. Thank You.
