Solid

This app has been helping me memorize basic strategy and learn what the actual percentage chances you have with each hand against the dealer.

Great Practice Tool

Great app for getting quick practice in. Any time I have a few minutes of down time I can open this app and get in hundreds of simulated hands that improve my response time and get where decisions are almost mindless. You just know what to do instantly.
