This app helps me a lot to improve my chess, but one thing is missing on the game is force move that actually important if any force move happen in game show as the best move but still it is very helpful app.
★★★★★Chisom· May 31, 2026
The app is best for analyzing chess games. I recommend it. Suggestions: * add AI to explain each moves depending on the position. * add personalities like Magnus and Hikaru * add bots tournaments

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. 🥰

Old version good, new version giving wrong accuracy, I am 2000 plays, but it's saying play style 800
★★☆☆☆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?
★★☆☆☆Josh Pearson· May 28, 2026
It's either the sensitivity of my phone screen or this app that's causing a lot of accidental moves. They can be undone during a game but since the engine tries to force a draw when it's losing, they often lead to an immediate draw or mate in the endgame. Otherwise, it's a good app for learning chess.
★☆☆☆☆Lcd Drmr· May 25, 2026
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.
