There are lots of such programs, m8.
I have personally tried Calculatem Pro, Holdem Pirate and Poker Indicator.
There are also Poker Sidekick, Pokerbility, and Poker Pro 2006, all of which have reasonably good reviews, and probably ten more besides.
Of those I`ve tried, I liked Calculatem Pro the best, but they really all do the same thing and differ mainly in the details of the interface and in which poker rooms they support.
A tool of this sort is of some help as a training aid, to help you develop your ability to appreciate pot odds
and to estimate the relative value of your hand in various situations. Beware of the publishers` hype, though. Most of their websites would have you believe that all you need do is follow the guidance given by their tool and you`ll become a world-class player overnight. Garbage ! They`ll help steer you away from beginner`s errors, that`s all.
