Hi everyone! 👋 I’m the developer of iOS app Chess.PhD - Chess Puzzles: Tactics Trainer , and I’d like to share a project I’ve been building for the chess community. Right now the app contains over 5 million puzzles, making it one of the largest puzzle databases available. The puzzles adapt to your level, so you always get challenges that are tough enough to help you grow, but not overwhelming.  Key features:

  • 🔥 5 million puzzles for all levels (400-2800)

  • 🎯 64 tactical themes

  • 🧠 Smart algorithms that adapt to your level

  • ⚙️ Built-in engine that explains your mistakes, move by move

  • ⭐ Favorites & History – save puzzles you like and revisit your solved ones anytime.
The app is completely free for now – no hidden paywalls or limits. What I’m working on next:The big next step is developing a smart model that explains positions in human language. Instead of just showing centipawns or engine lines, it will describe concepts. In short, it won’t just say what the evaluation is, but why. I believe this can make learning tactics and strategy far more intuitive and enjoyable. I’ve already received great feedback from several GMs, which inspires me to keep pushing forward. 👉 Link to the app on the App Store or type Chess Puzzles & Tactics Master in search if you don't like links. I’d love for you to try it out and share your impressions. Your feedback will help shape the next generation of chess training tools. If you like it, please share with your friends. Thanks a lot for your support! 🙏

Nice and free, super cool!

Made by enthusiast, who really loves chess and understands a lot, not by random IT team with foolish spec and no real chess context.

Looking forward for PC or Android version!

Very impressive app!
I particularly appreciate the complexity and uniqueness of the tasks. I haven't encountered any of these tasks before, so I have to think carefully about each one.

So you're using the Lichess puzzles? That's reasonable, I guess. Anyone is allowed to do anything they want with that data, including sell it. You should mention it, though.

The app is pretty cool! I enjoy the puzzles there more than on chess.com lately.
