## What is Shredder Chess?

Shredder, the most successful chess program ever, is now also available for the iPhone. You can play against Shredder, analyze with him and solve chess puzzles. It offers the usual Shredder standard for your pocket.

In addition to the outstanding playing strength of the 12 times computer chess world champion, Shredder is also able to mimic the play of a human chess player with any playing strength. He even deliberately makes typical human mistakes in those levels.

Solve 1000 built in chess puzzles. Shredder keeps track of your performance and offers advice if needed.

You can adjust Shredder’s playing strength from beginner to master level. If you like, Shredder automatically adjusts his strength to yours. He even calculates an Elo rating for you. This is how the playing strength of chess players is typically measured.

### 5/5 — GOAT

*2026-06-28, version 1.11.0*

There is no chess trainer better than this app. Used it for years. Try it out and you won’t be misled. Thanks for keeping this up and American for as long as you have. God bless, and play chess. SHRED.

### 5/5 — 360 Chess mode?

*2026-03-19, version 1.11.0*

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!

### 5/5 — Old school

*2025-08-07, version 1.11.0*

Cette appli est clairement has been, mais très sincèrement, elle cartonne ! Elle a tout ce qu'il faut pour jouer : analyse, coups conseilés, 2600 élo, possibilité de setup les coups pour les deux camps, ou faire des boards puis lancer la partie sur quelques problèmes à étudier, elle évalue votre jeu et adapte son niveau progressivement, c'est pas un coach, c'est pas chess.com, mais c'est quand même une super app, si vous dépassez le côté un "cheap".

### 5/5 — Danke für die kontinuierliche Arbeit an der App!

*2025-07-30, version 1.11.0*

Auch nach Jahren kontinuierliche Arbeit an der App! Und das kostenlos. Vielen Dank und weiter so!

### 1/5 — Outdated App with Limited Features

*2025-04-25, version 1.11.0*

I recently bought this chess application, and I must say I'm quite disappointed. The interface feels outdated, and it lacks many features that modern chess apps offer. 

For example, there are no tutorials for beginners or advanced strategies, which makes it difficult for players to improve their skills. Additionally, the graphics and overall user experience could use a significant update to make it more engaging.

I believe this app has potential, but it needs a thorough revamp to compete with more current options on the market. I hope the developers consider these improvements in future updates.

### 5/5 — Best of the Best

*2025-02-03, version 1.11.0*

Look no further! Shredder Chess is the GOAT

### 5/5 — Best Choice

*2024-11-05, version 1.11.0*

I have had this program for so many years that I have gone through not just on my PC but to iPhone and on my MacBook.  I recommend this program 100%

### 5/5 — thanks for the voiceover accessibility

*2024-08-04, version 1.11.0*

Shame on the other chess app developers who neglect and disregard the blind chess players being lazy to make their apps accessible for the visually impaired.

### 4/5 — Great app, but got puzzle scoring problems

*2024-08-03, version 1.11.0*

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.

### 5/5 — Best chess app hands down

*2024-02-25, version 1.11.0*

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.
