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.

Product direction

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.

Joseki Encyclopedia

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.

First lesson

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.

Territory

Black converts the corner into countable territory.

Base

White builds a side base with the vertical frame.

Efficiency

Too small wastes direction; too far leaves leaks.

Web Study Desk

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

01

Larger-board review for positions that need room, context, and less thumb navigation.

02

Variation work built around candidate branches, ownership shifts, and human-readable study notes.

03

Sharing workflows for lessons, review records, and teacher/student handoff.

04

Future tutor workflows layered on top of GoReview's review and practice data.

Learning loop

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.

01 Review with KataGo Score delta against the engine's top candidate flags your mistakes. 02 Save as problem Focus region crops the swing. The correct move becomes the answer. 03 SM-2 spaced repetition Again / Good / Easy. Next review in days, weeks, or months. 04 Daily practice set Due mistakes plus life-and-death, mixed into one daily streak.
Mistakes become problems

After a KataGo review completes, any score-delta swing becomes a tsumego-style problem — setup stones, correct move, focus region.

SM-2 spaced repetition

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.

Reminders that guard your streak

Pick a time. GoReview nudges you before a streak breaks and stays quiet once you've finished today's set.

A progress dashboard, not vanity stats

Streak calendar, 30-day accuracy, solved totals, and a seven-day due forecast — pulled from your real attempts.

Your puzzles never flood the queue

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.

Puzzle library

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.

Browse offline

The full collection index ships in the app and refreshes weekly — search and filter without a network round-trip.

Filter by rank

Beginner, intermediate, and dan bands narrow 4,000+ collections down to the ones matched to your level.

Sort by difficulty

Order collections by difficulty or rating, then preview a set before you commit to downloading it.

Drop into daily practice

Downloaded collections feed the life-and-death half of your daily set, in order, one collection at a time.

Current app

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.

Engine

KataGo with CoreML on iPhone and iPad.

Mobile review

OGS sync, SGF import, review, capture, and practice — analysis is cancellable and resumes from where it stopped, even after a force-quit.

Knows your rank

Set your rank once; mistake detection tightens from 3-point swings for kyu players to under a point for dan.

Privacy

Game records and board state are not sent to GameBoardLab servers.

Next surface

The Web Study Desk is in development and should not be treated as available yet.

iOS now · Web next

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.

iPhone and iPad

Available now for mobile review, OGS game intake, mistake capture, and spaced-repetition practice.

Web Study Desk

In development for larger-board review, variation work, sharing, and future tutor workflows.

Mac desktop

Paused for public new-user downloads while product development concentrates on Web + iOS.

Every game you already play

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.

Shipping

OGS

OAuth connect to your OGS account. Completed games sync automatically, ready to review.

Shipping

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.

Shipping

P2P face-to-face

MultipeerConnectivity pairing for club night. Finished games save straight to your library.

Roadmap

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.

Guides

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.
