GoReview is the iPhone and iPad Go reviewer that turns every game you play into your personal learning library — local-first, on-device KataGo, no subscription. YOUR LIBRARY, EVERY SOURCE • OGS: sign in once and your finished games sync automatically. • Other servers: drop SGF or Tygem .gib files into the GoReview folder in iCloud Drive — they appear in your library on the next launch. • Batch import: select multiple SGF files at once, with per-file progress and a result summary. Duplicate games are skipped automatically. • Face-to-face: play someone next to you on another device over a local Wi-Fi peer-to-peer connection. No internet needed. • Same device: play the AI at 7 strength levels, or hand the iPad back and forth between two players. • iCloud sync: your library follows you across iPhone and iPad, with conflict hardening that catches missing-game scenarios before overwrites happen. REVIEW BECOMES PRACTICE • On-device KataGo reviews your full game in seconds — top-3 candidate moves on the board, win-rate chart, territory overlay (Benson), move-by-move commentary written into the SGF when you export. Mistake detection adapts to the rank you set—kyu players see the big blunders, while dan players catch finer slips. Cancel analysis at any time; completed moves stay saved, and you can resume from the checkpoint with an estimated time remaining. • One tap turns each mistake into a practice problem in your personal library. The AI prefills a solution line and likely failure variations. • Author your own twist: replace the suggested move, write why it works in your own words, add the failure paths you actually want to remember. • Solve as multi-move sequences with SM-2 spaced repetition — not single-guess flash cards. • Interactive review: tap the board to branch a variation, the AI re-analyzes, step back and the original game resumes. No modals, no menus. • 9×9, 13×13, 19×19. Japanese, Chinese, Korean, New Zealand rules. • Pinch to zoom, long-press to preview, board sounds and haptics. • Localized in English, 繁體中文, 简体中文, 日本語, and 한국어. TEN PROBLEMS A DAY, A REASON TO COME BACK • Daily practice: due mistake reviews and rank-matched tsumego form one fixed set. Finish it and you're done—not an endless queue. • Streaks, badges, and reminders: choose a time; GoReview nudges you when your streak is at risk, and stays quiet once you're done for the day. • Progress dashboard: streak calendar, 30-day accuracy, total problems solved, and the next 7 days of due reviews—see yourself improve. • 4,000+ OGS collections: browse offline and filter by rank. Download a collection into daily practice; finished for today but want more? Keep solving from the same collection. PRICING GoReview is free. The free tier includes 1,000 saved games and unlimited AI analysis — enough to make this your everyday review tool. Premium is a one-time purchase that lifts the library cap. No subscription, ever. Family Sharing supported. FOR WHO Whether you're a kyu player trying to break through to dan, a single-digit kyu who wants the bot to actually punish your overplays, or a serious amateur who just wants the strongest pocket review tool — GoReview is built for you. Built by a Go player who got tired of every other reviewer either being a web app, a paid subscription, or both. --- SUPPORT https://gameboardlab.com/goreview/support PRIVACY POLICY https://gameboardlab.com/privacy
