Good concepts but mediocre execution
The app is buggy. For example after ending a game, it isnt possible (or at least very unintuitive) to start a new game with different settings: clicking Play in the left side menu just takes you back to the ended game screen. Also the rapid analysis tool does not provide consistently accurate advice; supposedly better moves are suggested that clearly lead to your pieces being captured without recourse. The rating system is also buggy because the numeric figure stated by your username is not updated after each game or even after several games.
Overall good ideas but often frustrating to use.
