## What is ChessBase Mobile Chess?

ChessBase Mobile is the training, playing, and analysis platform for chess players who track their progress by the numbers.
ChessBase Mobile is built by ChessBase, the company behind the standard desktop software used by world champions and club players alike for over 30 years.

Solve tactics puzzles rated by difficulty and watch your Elo rise or fall with every attempt. No participation trophies, your rating reflects exactly where you stand. The tactics database draws from positions in real games, not synthetic exercises, so the patterns you train are the patterns you encounter at the board.

Puzzle Fight puts you head-to-head against another player in a timed series of 24 tactical positions. Both players solve the same puzzles simultaneously. The one who solves more, faster, wins - and gains Elo. Structured competition, not a casual minigame.

Play live games in Blitz and Rapid formats against opponents worldwide. Premove support, clean interface, no clutter.

The ChessBase Online Database contains over 14 million games. Search by player, position, or opening. Review grandmaster games, study endgame structures, track opening trends - the same database used by professionals, accessible from your phone.

Cloud analysis with several engines, including Fritz and Lc0. Basic cloud analysis with Fritz is free. For deeper analysis, scalable cloud servers are available, from Large to Gargantuan, paid per minute in ducats. Lc0 brings neural network evaluation for positions where classical engines struggle. The engine panel shows evaluation, depth, and principal variation.

Build and maintain your opening repertoire in the cloud. 300 opening overviews with repertoire suggestions help you get started with new systems. A live opening book provides up-to-date statistics for every position. Three practice modes let you drill your variations until they stick.

Annotate your games with comments, symbols, variations, arrows, and markings. Save games and analyses in cloud databases that synchronise across all your devices. Share positions and games via link, image, GIF, FEN, QR code, or PGN. Upload and download PGN files for full compatibility with desktop software.

AI Kibitzer provides live commentary during games and puzzles — with personality. Chess-legend anecdotes, opinions, the occasional bad joke. Like a friend with too much chess trivia sitting next to you. Audio output included.

Available in 27 languages. Customisable board colours, piece sets, and notation display.

Light and dark mode across all screens, or set to follow your device preference. No ads. No energy systems. No artificial gating. Open the app, train, close the app.

Free to use, all functions are available at no cost. ChessBase Premium unlocks expanded cloud storage and unlimited database search results.

Free: search the online database (max 50 games displayed), up to 10 cloud databases (10 MB total), cloud clipping for up to 10 games.

Premium: unlimited database search, up to 200 cloud databases (500 MB total), cloud clipping for up to 400 games.

### 5/5 — A Turn in the right direction

*2026-06-07*

This app is the start of finally something for apple products. I currently have had to use VMare Fusion emulator to even run ChessBase on my laptop, but it only uses the slowest of stockfish engines :( I like that the interface is simpler than the original and relatively fast.  Makes it a bit easier to start. I would, however, like to see the following changes: 1) Notation and Analysis on the same slide. I need both at the same time for the level of prep I do. Toggling between both is highly inconvenient. 2) Some Control over the engine being used would be nice. 3) Hot Keys for faster editing (especially symbols)

### 1/5 — Turn off the arrows

*2026-06-02*

There’s still no way to turn off the annoying and distracting last move arrows in the app? Why is this forced? Give users the option to remove them. Until that happens, the app is worthless to me.

### 4/5 — Replay Training and Turning off Engine features missing

*2026-05-15*

Great step in the right direction. Chessbase is the best offline professional training tool and am happy there’s an app to support it and I can imagine it’s only going to get better.  It’s great to be able to access my games and the database without having to log into my computer.  

One of the great features the program has that I think would translate really well to the mobile app is replay training (aka solitaire chess).  Chessbase’s version of this type of training is simply the best I have seen as you can get a score and compare against the engine which helps gamify what can otherwise be a difficult task as you’re trying to replicate the moves of a great player.  While this exists in the app as Guess Variation, it doesn’t have the scoring and the engine comparison that exists in the program.  Would love to see this feature!

Also, I can’t turn off the engine.  Shows up as Let’s Check automatically and I often don’t want to see the engine when reviewing games!

**Developer response:** Thank you for the detailed feedback and the great suggestions. We’re glad you enjoy access to your games and databases on mobile. Replay Training with scoring/engine comparison is a very interesting idea for future updates. We also understand the request for better engine control while reviewing games.

### 5/5 — I’m satisfied

*2026-03-31*

Just need some optimisation, 
More helpful after subscription!

**Developer response:** Thank you very much for your feedback and your positive rating. We’re glad ChessBase Mobile is useful for you, especially with the subscription features. We have released a new version and continue to optimize performance, usability and the overall playing and training experience.

### 1/5 — The app seems stuck in the opening Menu

*2026-03-25*

I can’t open it

**Developer response:** Sorry for the trouble. Please update to the latest version of ChessBase Mobile, released after 28 April, and try again. We have worked on stability and startup behavior. If the app still does not open, please contact our support with your device model and iOS version so we can investigate it directly.

### 1/5 — Fix it

*2026-03-01*

Now the remote engine is not starting

**Developer response:** Thank you for reporting this. The engine start should of course work reliably. Please install the latest version of ChessBase Mobile from the App Store. If the problem remains, please send us your device model and iOS version so our team can reproduce and fix the issue.

### 2/5 — Power idea, frustrating interface

*2026-02-17*

Great idea and huge potential, but the app is frustrating to use seriously. It works well for quickly finding and viewing games or checking lines, but using it as an actual portable database is almost impossible. The interface is inconvenient and often non-intuitive. Saving games, organizing them, or building personal databases does not work reliably — as the number of games grows, access to the database simply disappears and only empty loading rows appear. The concept is excellent, but the current implementation makes serious use very difficult.

**Developer response:** Thank you for taking the time to write such detailed feedback. You are right: the strength of ChessBase Mobile should be quick access to games, training, analysis and databases without unnecessary friction. The new version is a step in that direction, and we will continue improving navigation, cloud access and game handling. Feedback like yours is extremely useful for prioritizing the next updates.

### 1/5 — Can’t paste games into the mobile app

*2026-02-14*

I subscribed so I can paste games from chess.com and analyze them but apparently there is no way to do this in the app. Useless

**Developer response:** Thank you for the suggestion. Importing and pasting games is an important use case for many players. Please make sure you are using the latest version of ChessBase Mobile. We are also reviewing how PGN handling and game import can be made easier in future updates.

### 1/5 — Original Customer Before the Subscription Update

*2026-01-20*

I purchased this app when it was first developed. Now I am expected to pay a subscription for features I had in the old app. You decided to throw your original supporters under the bus. The right thing to do was grandfather customers who brought the app in the first year of development with a free subscription.
Simply put; THIS IS GREED.

**Developer response:** Thank you for your honest feedback. We understand that subscription changes can be frustrating, especially for users who have supported ChessBase for a long time. Our goal is to keep ChessBase Mobile sustainable while continuing to improve the app. Please contact our support team so we can review your specific case.

### 1/5 — Contraseña

*2026-01-12*

No permite recuperar la contraseña. No me acuerdo cuál era.

**Developer response:** Gracias por el aviso. El acceso a la cuenta debe funcionar de forma fiable. Por favor, póngase en contacto con nuestro soporte para que podamos ayudarle a recuperar el acceso. También estamos trabajando para que los procesos de cuenta y contraseña sean más claros dentro de la app.
