How it works

🛠️ Create Your Repertoire

With Chess Prep Pro, you can create custom comprehensive chess openings. Create an opening repertoire by saving move reponses that you wish to remember for any opponent move. Use the blindspot finder feature to eliminate blind spots from your repertoire and maximise your coverage.

🎯 Train Your Repertoire

Once your repertoire is set up, it’s time to train. The app presents positions from your repertoire, challenging you to recall the correct moves. Practice your openings, focus on specific lines, and use advanced filters & settings to sharpen your skills. The app even remembers your most missed moves to help you target your weak spots.

🚀 See results

With consistent practice, you’ll see your opening game transform. Never get caught off guard in the opening again. Suprise your opponent with the speed, confidence and accuracy that you play your openings with. Chess Prep Pro ensures that your openings become one of your strongest assets.

“Very helpful app! Would recommend, especially if you are a beginner to chess. It helps you build your repertoire, which is a really important factor when it comes to being a better chess player. It’s super simple, not complicated at all. It offers repertoires free to download if you don’t know how to build your own. Very customizable; you can change the color scheme to your liking. Also, it is very accessible even without premium. It’s amazing!”




“The app’s great, easy to set up with the import options and I think that it is one of the best training methods, the app has already helped me gain 200 elo points”




“Love it! I had a lot of time looking for a good app to enhance chess openings. With this app, you can use their repertoires or upload your own studies. Likewise, the interface is intuitive. It’s similar to ChessBase for the tool to try openings, but it’s easier to use and from your smartphone.”




“Absolutely the best app to study chess openings! Graphic interface is based on Lichess, you can go on without move limits (this is not possible with other similar apps), and so you can study every branch of an opening and win chances of each move.”
