PokerStove is a free piece of software that allows you to calculate equity in Texas Hold'em poker. Punch the hands in for the respective players and PokerStove will quickly evaluate the pre-flop odds, showing you whether your hand is a favorite or not.

Poker Stove only exists for Windows. So we've created a similar program that works on your Mac. We call it PokerZebra. Think of it as PokerStove for Mac.
