Study the games
you actually play.
Review the games you play on iPhone and iPad, and turn the important mistakes into practice.
One loop. Every game.
Every GameBoardLab app runs the same method — collect the games you're already playing, AI-review them on your own device, turn mistakes into spaced-repetition problems, and come back to the shapes you keep getting wrong. Same loop, same design language, same respect for your time.
GoReview
GoReview helps Go players turn real games into review and practice. The iPhone and iPad app is available now.

ChessReview, and more.
The same loop, but for chess — and later, any classical board game with a strong on-device engine. Same SRS queue format, same local-first data, same design language.

Tools that don't get in the way.
Beyond the review loop, we also build small, focused tools for the moments when you're actually at the board. The first one is shipping.

More table tools.
A pattern: small, single-purpose, no-noise tools that earn their place beside a real board. We'll keep it short.
Quietly serious software.
Four principles that show up in every product we ship.
A loop, not a library
Every app is built around the same practice cycle: collect games, AI review, mistakes become spaced-repetition problems, practice, improve. Buying one of our apps buys into a method, not a pile of features.
Local-first
In the shipping GoReview app, review data stays local and sync uses your iCloud. We do not run GoReview game-record servers.
Focused surfaces
GoReview starts where study is easiest to keep up: iPhone and iPad today, then the browser for deeper review when a larger board matters.
No noise
No in-app ads. No in-app analytics. No nag screens. No upsell pressure. The product earns its place on your device.
Start with GoReview.
iPhone and iPad are available now on the App Store. Larger-board review in the browser comes next.
