Brain Flipper は、英語を「学ぶ」アプリではありません。 日本語から英語へ変換するときの思考構造そのものを、反射レベルで行うトレーニングアプリです。 文章の意味ではなく、語順と構造に集中。 間違えた構造だけを自動で集め、弱点として繰り返し鍛えます。 説明は最小限。テンポは止めない。 英語を考える前に、英語の形が先に出てくる感覚を育てます。

Tap the squares in the order the return marks tell you to. Each puzzle takes seconds to solve — and the more you play, the more classical Chinese (kanbun) you can actually read. ■ Four ways to play • Order Puzzle: plain squares and marks only. Starts with the simplest mark and opens up through the full set as you go • Kanbun Puzzle: put the characters in reading order, then see the reading and its meaning • Mark Placement: read the sentence first, then work out where each mark goes — the puzzle in reverse • Read Kanbun: browse well-known passages at your own pace, no pressure ■ Built to keep you playing • New mark types unlock gradually as you progress • A wrong tap tells you exactly which character was out of place • Undo any tap instantly; stuck players can watch a short video for one hint ■ Along the way, you learn to read kanbun • Passages are drawn from public-domain classical texts, including the Analects • Solve one, and you get its full reading and a plain-language explanation of what it means ■ Easy to use • Core puzzles work offline. Content updates, ads, purchases and restores require a connection. ■ Premium plan (one-time purchase) • Ads removed • All chapters unlocked ■ Good for • A quick mental warm-up in a spare five minutes • Getting return-mark rules to stick before a test • Actually reading famous classical passages, not just memorizing them Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
