Quite simply the best chess app I have played on mobile Chassis has everything you need to become a better player Lots of game engines too My favorite engine is Maia which will make mistakes you can exploit
★★★★★Arman Heydari· Jun 27, 2026
Very good, perfect analysis, great shape. Good, the appearance and strong engine. And it's the best app for analysis if you want
★★★★★Hamy To Harimanana Ranirison· Jul 3, 2026
This app is amazing so far especially with the offline reviewing, with each move shown a strength. I suggest an update where you would be able to have your position constantly analyzed & displayed while playing the game or setting up a board, to be able to toy around with more freedom and possibilities. For example, it would be useful when playing against an AI when it makes illegal moves. It also works to test positions & theories of some sorts. Overall, I have no complaints. Keep it up!

Old version good, new version giving wrong accuracy, I am 2000 plays, but it's saying play style 800
★★☆☆☆Patrick· Jul 23, 2026
The game freezes on the 7th or 8th move the computer player plays. The computer player just sits there and after starting a new game, it does the same thing ☹️ 7th or 8th move every time.
★★☆☆☆GR Terry· Jun 29, 2026
The app is made for tiny hands. They have an inch and a half of dead space, but they cram everything on top of everything else so my normal-sized fingers often hit the wrong button, despite hitting the same spot on the screen. Also, there is no way to avoid having your review interrupted by a big game report which needs to present itself without being asked. Why can't I review the game without the popup screens? Also, why not make a different version for people with normal-sized fingers?
