OneSolve Go runs KataGo directly on your iPhone or iPad. Models and problem packs download on demand from the App Store when first needed. Once downloaded, play, problems and local review work offline. Optional online features are also available. FROM 20 KYU TO 9 DAN+ · The kyu levels are not a weakened engine. They use a network trained on human games — it misses things, gets greedy and plays a loose endgame, like a person rather than a machine playing badly on purpose · The dan levels are set by KataGo's search depth, one rung at a time · 9x9, 13x13 and 19x19, with handicap 13,934 LIFE-AND-DEATH PROBLEMS Life and death, capture, tesuji and endgame, graded by type and five difficulty levels, all solvable offline. 33 BEGINNER LESSONS Ordered after the British Go Association's teaching guide: capturing first, boards up to 9x9 to begin with, ko last. The graduation test is beating KataGo on 9x9 with a 4-stone handicap. REVIEW AND RANK ASSESSMENT Let KataGo analyse a finished game move by move: it draws the win-rate curve and picks out the moves that cost you most. The rank assessment estimates your strength from move quality, not from the result. TUNED FOR APPLE SILICON · Prefers the Neural Engine — same strength, less battery · Low power / normal / full speed, with automatic downgrade when the device heats up · SGF import and export; games sync across your devices through iCloud ONLINE FEATURES AND PRIVACY Share a selected game as a revocable web link. AI explanations use your own configured provider and API key, sending your questions and relevant game context to that provider. Keys stay in the local Keychain; provider charges may apply. No manual registration or sign-in is required. Membership and rewards services process random device/account identifiers, purchase receipts and learning-task progress. After privacy consent, model sessions report device/OS details, CPU/memory use, thermal and battery status, and disk/network counters. Apple provides payments and iCloud synchronization. There are no ads or cross-app advertising tracking. — Membership & Subscription — · Yearly Membership: auto-renewable subscription, 1 year; price shown in-app for your storefront (CNY 38/year in China).
