I am using 2 training apps on my Iphone. One is BJA (Blackjack Apprenticeship) trainer pro and the other is Blackjack 101 pro that tests you on basic strategy. Any thought on using these apps? They seem to work fine for me but I find it hard to get ahead on the BJA pro app. I start betting low and raise it accordingly with the positive true count. It seems though that when I have a good positive count that it is helping the dealer more than often.
