Best Analysis App for Android and Just Got Better! The Rating Function is Wonderful, I used to Wish for a Numerical Rating in Addition to an Accuracy Rating I'm a very strong player with Accuracy from 90-99.7 rating just had a game I analyzed with a 94.1% rating and a 2630 rating not my best accuracy rating but the other player got a 2240 rating I really feel I'm improving using this app. I'm using the Stock fish engine 18 when it was first available, and now it's available for Chassis Pro. 🥰

The only problem is if I change default engine to OEX engine cannot move the engine vs human, but it works on engine vs engine.

When adding variations to be analyzed, there's no need for the pop-up notification stating how many variations are now being analyzed. The number being analyzed is obvious, & the pop-up just covers the variation analysis lines, so I waste time waiting for it to disappear, so I can actually see the variations. Otherwise, the program works well (though sometimes can't scan obvious chessboard screenshots correctly) and the ability to scan screenshots onto the chess board is extremely useful.

It was my favorite chess app. However with latest 1 or 2 new versions the interface got awful because when I analyze a game now I can only see maximum 1 line of engine variants instead of 2 with older version that fit on screen. And additionally now sometimes that annoying "Why mistake" message appears which I cannot disable, that makes engine lines not visible during analysis. Please revert the graphical interface changes, and please make "Why mistake" message optional

Old version good, new version giving wrong accuracy, I am 2000 plays, but it's saying play style 800

Since the May 2026 update, the graphics have been improved a lot, but the entire analysis is useless. This is because the quick analysis now needlessly takes about 4 times longer but is limited to the same 14 depth, yet gives crazy high wrong values. Before, we could let analysis run as deep as we wanted by stepping slowly through the moves (total 3 mins), now have to pay, and it has a depth limit of only 18. And it's likely just as inaccurate as the quick one, anyway. A good program is ruined.

world's most engine and app of all time I used it first it was 0.80 + eval for my opponent, and then I played engine moved, and it then made me losed at end by 12 + eval
