GoReview for iPhone, iPad, and the upcoming Web Study Desk.
GoReview helps Go players turn real games into review and practice. The iPhone and iPad app is available now for mobile study. We are building a browser-based Study Desk for larger-board review, variation work, sharing, and future tutor workflows. The earlier Mac desktop app is paused while development focuses on Web + iOS.
Available now: iPhone and iPad mobile review.
In development: Web Study Desk for deeper browser-based study.
Paused: public Mac desktop downloads for new users.

Learn the shape before the engine line.
A clearer reference layer for common corner patterns: territory, base, efficiency, common beginner mistakes, and the human question behind the AI recommendation.
Star Point Kosumi-Tsuke Joseki
An interactive board walkthrough for kosumi-tsuke, extension, jump, small knight, and the three-space base. The point is not to memorize a long sequence. It is to see when the local shape is settled, how Black takes corner territory, how White builds a base, and which common mistakes waste efficiency.
Black converts the corner into countable territory.
White builds a side base with the vertical frame.
Too small wastes direction; too far leaves leaks.
A larger-board study desk is in development.
We are building a browser-based Study Desk for larger-board review, variation work, sharing, and future tutor workflows. It is not available yet, but it is the next major GoReview surface.

Tutor layer
planned
Ownership swing
+7.1
Larger-board review for positions that need room, context, and less thumb navigation.
Variation work built around candidate branches, ownership shifts, and human-readable study notes.
Sharing workflows for lessons, review records, and teacher/student handoff.
Future tutor workflows layered on top of GoReview's review and practice data.
A daily practice habit, not an endless queue.
Review is only half of getting stronger — the other half is coming back before you forget. GoReview builds a fixed-size daily set that mixes your due mistakes with level-matched life-and-death, resumes where you left off, and keeps a streak. Ten problems a day beats a thousand-item backlog you never open.
After a KataGo review completes, any score-delta swing becomes a tsumego-style problem — setup stones, correct move, focus region.
Rate each attempt Again / Good / Easy. The next review lands days, weeks, or months out — the shapes you miss come back sooner than the ones you nail.
Pick a time. GoReview nudges you before a streak breaks and stays quiet once you've finished today's set.
Streak calendar, 30-day accuracy, solved totals, and a seven-day due forecast — pulled from your real attempts.
Downloaded collections sit in a separate library track. A shape only enters spaced repetition after you actually miss it — so Due Today stays honest, not a thousand-item backlog.
4,000+ life-and-death collections, sized to your rank.
Daily practice needs material. GoReview ships an offline index of the full OGS puzzle library — browse by rank band, sort by difficulty, and download a collection to drill. No account needed to look around.
The full collection index ships in the app and refreshes weekly — search and filter without a network round-trip.
Beginner, intermediate, and dan bands narrow 4,000+ collections down to the ones matched to your level.
Order collections by difficulty or rating, then preview a set before you commit to downloading it.
Downloaded collections feed the life-and-death half of your daily set, in order, one collection at a time.
On-device review where GoReview ships today.
The current product focus is the iPhone and iPad app: import games, run review on device, save the important mistake, and keep practicing without sending your game records to GameBoardLab servers.
KataGo with CoreML on iPhone and iPad.
OGS sync, SGF import, review, capture, and practice — analysis is cancellable and resumes from where it stopped, even after a force-quit.
Set your rank once; mistake detection tightens from 3-point swings for kyu players to under a point for dan.
Game records and board state are not sent to GameBoardLab servers.
The Web Study Desk is in development and should not be treated as available yet.
GoReview is becoming a Web + iOS study system.
iPhone and iPad are available now; the Web Study Desk is the next major surface. The earlier Mac desktop app is paused while development focuses on this direction.
Available now for mobile review, OGS game intake, mistake capture, and spaced-repetition practice.
In development for larger-board review, variation work, sharing, and future tutor workflows.
Paused for public new-user downloads while product development concentrates on Web + iOS.
Bring games from anywhere.
Wherever you play, your games end up in one reviewable library — and every new source lands in the same SRS queue. No extra account, no re-entering games by hand.
OGS
OAuth connect to your OGS account. Completed games sync automatically, ready to review.
SGF
Import one file or fifty — batch import shows per-file progress, skips duplicates, and fills your free quota before stopping. Files never leave your machine.
P2P face-to-face
MultipeerConnectivity pairing for club night. Finished games save straight to your library.
More servers
KGS, Fox, Tygem, IGS — more online Go servers on the roadmap as the OAuth work lines up.
Whatever source a game came from, the review pipeline is identical — KataGo evaluates on-device, the engine flags the score-delta swings, and any move you mark becomes a spaced-repetition problem in the same queue.
Workflows for the games you already play.
Practical articles for moving finished games into review, reading the AI output, and turning mistakes into repeatable practice.
iPhone and iPad now. Web Study Desk next.
GoReview is becoming a Web + iOS study system for Go players. iPhone and iPad are available now; the Web Study Desk is the next major surface.
