What it does

A coach who tells you why

Not just an engine that beats you. Each coach plays at its own level, reacts to your moves, and helps you see what you missed.

A coach that talks you through it

Every coach has a face that reacts to your moves and words for each one: what was good, what went wrong, what to try instead.

Every move graded

Brilliant, best, good, inaccuracy, mistake, blunder: a badge lands on your piece the moment you move. Made a mistake? Take it back and try the better move.

See why it was a mistake

Review any game move by move. Tap "Why was this a mistake?" to see your winning chances drop, the reply you missed, and the line the better move leads to.

Hints when you're stuck

Ask for a hint and get a nudge first. Ask again and it gets more specific, until it shows you the move.

Find the mistakes you repeat

Enter your Lichess or Chess.com username. Mistake Patterns analyses your recent games and shows the habits that cost you most, with every example.

Every game, kept

Your games against the coaches are saved on your device, with your record against each coach, ready to review whenever you like.

Questions

Good to know

Do I need an account?

No. There's nothing to sign up for. Open the app and play.

Does it work offline?

Yes. Stockfish 19 runs on your iPhone or iPad, so the coaches, hints, grades and reviews all work without a connection. Only Mistake Patterns needs the internet, to download your games from Lichess or Chess.com.

How strong are the coaches?

They range from 800 to 3190. Below 1320 the coach picks among Stockfish's good and not-so-good moves, the way a beginner would; from 1320 up it uses Stockfish's own rating limit, and the last coach is Stockfish at full strength. Now and then a coach slips on purpose, to see if you spot it.

Which devices does it run on?

iPhone and iPad with iOS 17 or later. On iPad, and on iPhone Duo when it's open, the board and the coach sit side by side.

What does it do with my data?

Nothing leaves your device. There are no accounts, no analytics and no ads. Mistake Patterns asks Lichess or Chess.com for the public games of the username you type in, and that's all. See the privacy policy.

I bought the unlock on another device. How do I get it here?

Open the coach picker (New game, in the ⋯ menu under the board), tap a locked coach, then "Restore purchase". The unlock comes back on any device signed in to the same Apple Account.

Ready to beat your coach?

Two coaches are free. The other twelve are waiting.

Privacy Policy

Beat Chess! Coach for iPhone and iPad · Effective 30 October 2026

In short: Beat Chess! Coach collects no personal data. It has no accounts, no analytics, no advertising and no tracking. Your games and analyses stay on your device. The only thing it sends anywhere is a username you type into Mistake Patterns, to Lichess or Chess.com, to fetch that player's public games.

What the app keeps on your device

The app stores these in its own storage on your device. They are never sent to us or anyone else, and deleting the app deletes them:

  • The games you finish against the coaches (your game history), with the coach's grade and notes on each move.
  • Your settings: the last coach and colour you played, and the Mistake Patterns options (site, username, number of games, game speeds).
  • Whether you have bought the full unlock, so the app works offline.

The analysis is done by Stockfish, a chess engine that runs inside the app on your device.

Mistake Patterns and your chess games

When you use Mistake Patterns, the app asks Lichess (lichess.org) or Chess.com for the recent public games of the username you enter, and analyses them on your device. That request goes from your device directly to the site you choose; like any web request, it includes your device's IP address. We never see it. Lichess and Chess.com handle these requests under their own privacy policies. The app sends nothing else to them and does not sign you in.

Purchases

The in-app purchase is handled by Apple through the App Store. We receive no payment details and no information about you; the app only asks the App Store whether your Apple Account has bought the unlock. Apple's privacy policy covers the purchase.

What we don't do

We don't collect, store, sell or share personal data. The app uses no analytics, advertising or tracking tools, and contains no third-party SDKs that do. We don't know who you are or how you use the app.

This website

This website (not the app) uses Google Analytics to count visits and see which pages are read. Google Analytics sets cookies and receives information such as the pages you view, your browser and device type and your approximate location, under Google's privacy policy. You can block it with your browser's settings or the Google Analytics opt-out add-on. The website's fonts are loaded from Google Fonts.

Children

The app collects no data from anyone, including children.

Changes

If this policy changes, the new version will be posted on this page with a new date.

Terms of Use

Beat Chess! Coach for iPhone and iPad · Effective 30 October 2026

In short: Enjoy the app and learn from it. The coach's advice comes from a chess engine and can be wrong. Purchases go through Apple. Lichess and Chess.com are separate services with their own rules.

Agreement

By downloading or using Beat Chess! Coach ("the app") you agree to these terms. The app is licensed to you, not sold, through Apple's App Store; Apple's Licensed Application End User License Agreement also applies. Where these terms and Apple's agreement differ, these terms apply to the extent the law and Apple's agreement allow.

Open source

The app includes Stockfish, which is free software under the GNU General Public License, version 3, and the app itself is released under the same licence. Nothing in these terms limits the rights the GPL gives you.

Purchases

The full unlock is a one-time, non-consumable in-app purchase. Apple processes the payment and handles refunds under its own terms; to ask for a refund, go to reportaproblem.apple.com. You can restore the purchase on any device signed in to the same Apple Account. Prices can change, and what the unlock includes is described in the app at the time you buy it.

Coaching and analysis

The grades, explanations, hints and patterns come from a chess engine and automated analysis. They are meant to help you learn and can be incomplete or wrong. The coaches' strength ratings are approximate. Some coaches make deliberate mistakes for you to spot.

The coaches

The coaches are fictional characters. Their names, portraits and personalities are invented, and any resemblance to real people is not intended to depict them.

Lichess and Chess.com

Mistake Patterns uses the public interfaces of Lichess and Chess.com. These are independent services, not affiliated with Beat Chess!; your use of them is subject to their terms. Use the feature for your own games or other public games, and don't use it to overload those services.

Acceptable use

Don't use the app, or its analysis, to cheat in games against other people, online or over the board.

No warranty

The app is provided "as is" and "as available", without warranties of any kind, to the fullest extent the law allows. We don't promise that it will be error-free or always available, or that it will improve your rating.

Limitation of liability

To the fullest extent the law allows, we are not liable for any indirect, incidental or consequential damages arising from your use of the app. Our total liability for any claim relating to the app is limited to the amount you paid for it. Nothing in these terms limits rights you have under consumer law that can't be waived.

Changes

We may update these terms. The new version will be posted on this page with a new date; continuing to use the app after that means you accept it.
