The app has great potential. The lessons and news are well introduced. The “play” part is more optional, as it is quite unpolished (move sounds are very loud and do not match the device volume level, stockfish computer levels are raw (0 to 8), which is too technical to make sense of for new players. Devs, there are so many apps focusing on “playing chess” that you should really focus on the extra content, that’s your leverage to stand out.
