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).

内容要新,方法要硬。 课文不是 1967 年的英国,是今天的美国。274 课美国生活对话,从机场入境、租房看病到超市结账、办公室闲聊,每一课都是你落地之后当天就会用上的场景。方法照旧硬核:听、跟读、背。听得懂人,说得出口,才算学会。 【怎么练】 · 整课连贯朗读加逐句音频,点哪句听哪句,真人语速的美音 · 中英对照、只看英文、只看中文,三种模式随时切换 · 跟读模式:每句放完留一段空白让你开口,同时录下你自己的声音,念完立刻和原声对比 · 长按任意单词看释义、听发音,自动收进生词本,连着课文原句一起存下来 · 随身听:一课接一课自动往下放,中英文或纯英文两版,关屏、锁屏都能听,可定时关闭。通勤、洗碗、跑步都能练 · 离线下载整课音频,地铁上没信号也不断 【怎么编排】 课程分四阶,对应 CEFR 的 A1 到 B2: 一阶 A1 零基础起步,听懂最简单的问答,能自我介绍 二阶 A2–B1 应付日常生活,租房、看病、点餐都能自己办 三阶 B1–B2 听懂连续的对话和观点,工作场合能表达 四阶 B2–C1 听懂玩笑和言外之意 每一阶都标了目标词汇量和已上线课数,学到哪一步、还剩多少,一眼看得见。 【我们不做什么】 不做打卡奖励,不做连胜勋章,不做每天哄你一句「太棒了」。反馈只给数据。方法是硬的:听、跟读、重复,没有捷径,也没有废动作。 【隐私】 不登录也能用全部功能。登录(Apple、Google 或邮箱)只用来把学习进度和生词本同步到云端,换手机不丢。你的跟读录音永远只存在这台手机里,不上传。可随时在 App 内删除账号和云端数据。
