IPhone version is ten times better. Also after playing a game, it's good to review and play that game against the computer, learn from it. But the moment you receive checkmate you can't go back, you have to start all over again, this is not the case on iPhone, how can the same app be so poorly managed on two different OS's. No punishment for cheaters, no follow ups on reports. Game keeps not updating after each match. Connection issues every day. Very bad app.
