360 Chess mode?
The app works well on iPhone 17 series event though the update is a bit dated. Can we have 360 Chess option in our games? That randomised mode is frequently played in FIDE Chess tournaments these days, and I think it will be a good addition inside the app!

Great app, but got puzzle scoring problems
I love this app, have been using it for years. However, there has been a long standing problem with the way it calculates scores for puzzles. In particular, not all puzzles get included in the scoring. Sometimes you can play a few and the scores never get updated. Or sometimes you solve a few puzzles with the top score, but your average score actually goes down. I usually reset my score after every 100 puzzles, and so it’s not that hard to see whether it’s updating it and if it’s accurate. I’ll be happy to give it 5 stars if this gets fixed.

Best chess app hands down
I have tried every one I could find sand nothing beats this. The puzzles it gives you to solve are great and if you think it is wrong and your solution is better it lets you convert the puzzle to challenge the computer and it's always right.

Still rocks after 2 years of no updates
I believe this is my best purchase on a chess app on IOS. I spent $7.99 in Feb of 2013 for this and after 10 years and many IOS version updates Shredder chess still is my go-to chess app for puzzles, playing, and learning. 1000 puzzles is a lot, and the best thing is I can continue playing against the engine at the position where the puzzle is solved for endgame practice.

Avoid this App
This app is defective on many levels eg - declares draws when clearly not the case. There was only the black king on the board with 3 white queens, white rook and White Castle and it declared a stalemate draw - advised me to take back a checkmate move - frequently offers poor suggested moves - doesn’t clearly show when you have been put in check - no explanation on puzzles The list goes on. Don’t waste your money like I did. Get something else

Playing strength control not working
At the beginning of a game, the program works more or less at the preset playing strength. However, during the middle game it often pumps up its rating significantly (validated with Crafty). A player at a moderate 1600 should continue to play at this level until the end and not suddenly play flawlessly. This is particularly annoying during a Blitz chess game.

Competent, engaging, makes you better
This is the best substitute I have found for other actual chess players; the difficulty scaling is great and give a good, surmountable challenge.

It works, but get the lite version
The title says it all- this works well enough; but it’s slow and the puzzle solutions are full of problems. This app was highly recommended to me by two good players, so it’s disappointing to find several mistakes in their puzzle solutions within the first day using the app. I do like the customization of the board and pieces available and the fact that I can review and analyze other games, etc.; but the interface could be improved quite a bit. Overall, it’s decent for an easy way to ply against a bot of customizable difficulty but there are better chess apps out there.

PGN would be nice
Great app. It would be helpful for reviewing games to be able to copy/paste PGN or even FEN data. Another wish is for more than one best-moves line, though I’m not sure where it could be fit on the screen.

Rating bug
Great chess game I’ve been using for years. Suddenly there’s a bug where after a game the computer says it will increase its rating to the maximum (2600) difficulty, even if I lose. It used to work well and increment based on performance and it was my favorite feature.

Not Realistic
I’m getting sick and tired of this app. I’m a class A player (1800+) and like to play on the app on the rides home. No matter what setting I choose I get demolished at 1800. At the 1700 its too easy. I play live over the board tournaments all the time and rarely (never) do you see 1800 players attack wildly before they even develop. The app gets away with it because it has perfect calculation within a number of plays. If I wanted to play a harder level I would choose 2100+ in the settings. Please calibrate this app. If I wanted to play against a titled caliber player I would not choose the 180

Shedder RULES!
I absolutely LOVE this app! Shredder is by FAR the best chess app I’ve ever used. It’s breathtakingly FAST! Using it in “aggressive mode” is how I like to use it, because it makes every game FUN! Beyond the excitement of each game played that way, I find that taking additional time to study the record of each game solidifies my understanding of what the hell happened 🤔 🤣 A summary of all my experience doing battle with Shredder: among all the best living players I’ve ever gone up against — even the most accommodating, patient, informative, and generous of opponents — none has taught me

The best iPhone chess app
Shredder though getting old is still easily the best chess application in the App Store for iPhone or iPad.

My Favorite Chess App
This app is great. The developer has been very helpful, even with minor concerns. It is also accessible to blind people, which is necessary for me. I would recommend this app to anyone.

Best part is guidance and problem solving
I like the puzzles, the puzzles vary in difficulty level, so I do not find them too easy or too daunting. I keep on getting hints when I make mistake or I use analysis in the end. I would like some analysis for better lines in addition to the evaluation number.

Best chess app for analysis
I love this app. I review all my over the board games right away and save it. Works perfectly on the iPhone.

Great, with one caveat
This is a fantastic chess app - probably the best on the App Store. The biggest problem: I'm just really disappointed that you can play only one game at a time. You should be able to play multiple games you can toggle back and forth between. Right now, it's only one game at a time... Which makes it very slow for playing different positions or openings simultaneously. So that makes it a bit annoying to use as a self-teaching app.
