How much time do you play poker? I would say that in the beginning you don´t need any program, especially because you´re learning how to play Poker, read your opponents, understand the dynamic of the game and the mathematics behind the cards.
But , if you´re playing for a period of time, I recommend you , like they said, find a HUD - HM2 , PokerTracker 4 , Jivaro - of these 3, Jivaro has the best interface but doesn´t have many resources. To complete my game, I use SharkScope
too, to find out about my opponents.
