This app helps users understand the mathematical probabilities of improving their hands in Omaha-8 after the flop and turn. It is for educational purposes only and does not provide advice on how to play specific hands. Selecting 'New Hand' will deal a random hand and random community cards. However, any face-up card can be changed at any stage before the river by pressing and holding the card and choosing among the possible alternatives. After the flop and turn, the Odds tab displays possible player hands and their probability. After the final community card is displayed, a list of possible opponent high and low hands is displayed along with their likelihood below the player's hand.
