If you're looking for the best cribbage app ... – Cribbage HD Review

... you've found it! Easy to initiate a variety of different game types (i.e., AI, pass & play, local, or online) with great selection of display options. At first we preferred the physical game so only played turn-based games on this app, but have since come to appreciate the speed of peer-to-peer play. The option to receive player feedback is improving my game too!
