PokerStove is another poker odds calculator. It claims to calculate hand range equities using probability distribution. Pokerstove can calculate both pre-flop and post-flop equity given the community cards.
Since it's free I can't see any harm in trying it. It appears to be a legitimate well known poker product so I would feel safe trying it out. The best way to get a feel for poker probabilites it to play play play
