I picked this up recently. You can download a demo version for free and then decide if you want the full version. I'm just getting into counting and this is very nice for simulating playing at a full table (actually you can select the number of players) instead of dealing real cards in your kitchen. It also has counting drills, index drills, deck estimation drills, and pretty much any strategy (HiLO, KO, etc.....) built in.
The graphics and interface are a little dated and the voices are crappy but the info it contains is great.
