Ads show after EVERY move. Extremely annoying. The only time limit option is 5 MINS PER DAY. This is ridiculous given that a chess match takes 30-40 moves on average. So it could take 30x5x2=350 Days (1 year) to complete a single match. So this app is like old school chess by mail, except that today you have 5 days to cheat by using a chess engine. This app is not recommended for strong players, the field is weak. Also it is not recommended to improve your games, unless you have plenty, and I mean plenty of time. Also, this app does not have a chess engine to examine your completed matches, so good luck trying to improve using this app.
