The game reads my move intention correctly about 60% of the time, and the mistakes it makes on my behalf usually lead to disaster. Taking back a move is treated as if you are using a cheat- makes the game not "count". The UI is incredibly cluttered and frankly ugly. Analysis or "coaching" doesnt seem to do anything. Who knows. Lots of better apps and trainers out there.
