I have developed an app called "Donkey Tracker" that will create a simple HUD for use at live poker tables. It will display VPIP, PFR and a hand count, so you'll be able to see the basic stats for each player at the table using about three button clicks per hand.
Updates will include graphing and additional tracking for aggression factor, 3-bet, 4-bet, and squeezing stats, bankroll/session tracking, c-bet, ck raise %, donk lead, aggression by street, etc. The Android version is in development and should be released soon.

I'd like to hear suggestions for improvements and suggestions for a proper price. I want it to be priced to keep people who don't understand its purpose away from it, but accurately reflect its value to those who understand it.
