Build your own BJJ OS — your personal game blueprint. BJJCraft is an app that helps you turn your BJJ knowledge into a searchable, structured system you can apply and continuously improve. It was built from real competition and teaching experience by the head instructor of Tokyo Jiujitsu Club, a 2nd-degree BJJ black belt and multiple-time IBJJF champion. Even when people train the same way, some get stronger and others don't. The difference isn't talent. It's how well they organize and operate their own BJJ OS — their personal game system. Training notes, technique videos, flowcharts. BJJCraft brings scattered BJJ knowledge together and turns it into a system you can search, use, and continuously build upon — your own BJJ OS (game blueprint). AI in BJJCraft doesn't give you generic answers. It works quietly in the background to organize, search, and structure your data, helping you turn what actually works for you into long-term BJJ knowledge assets. Key Features ■ My Knowledge Daily training takeaways, videos scattered across social media or your phone, your personal technique flowcharts, and what you're currently focusing on in training. BJJCraft's organizing groups and AI support connect recording → organization → intention into training that actually makes you stronger. ■ Video & Notes Library Save techniques you've learned or studied with videos and notes. Organize them by position or custom groups, so you can instantly find the right technique for the right situation. ■ Flowcharts Visually organize technique sequences and decision branches. From positions to next transitions, and responses to your opponent's reactions, build your personal game blueprint step by step. ■ AI Search Assistant Search your own records using natural language. Find things like "positions where I get stuck in half guard" or "techniques I've been using a lot recently," directly from your own data. ■ AI Organization Support Automatically organizes videos, notes, and flowcharts based on your groups. Keeps your knowledge from becoming cluttered and ensures it stays reusable and practical over time. Recommended For - Your training notes and videos are scattered across your phone and bookmarks - You want to systematize your own techniques - Generic AI answers don't feel relevant to your game - You want to build a BJJ style that fits your body and personality - You want to turn your training history into a lasting asset Subscription Basic features are available for free. 【BJJCraft Standard Plan (Monthly)】 Price: $4.99/month Duration: 1 month (auto-renewable monthly subscription) Free Trial: 14 days Includes: Expanded AI search and organization features, larger storage capacity, unlimited training notes Payment will be charged to your Apple ID account at confirmation of purchase.

「昨日より強くなっている気がしない」「練習記録アプリを入れたけど、入力が面倒で挫折した」 そんな格闘技の初心者〜中級者のために生まれたのが、AI格闘技コーチ&上達トラッカー『RollQuant(ロールクアント)』です。 面倒な勝敗や細かい技の手入力は一切不要。練習後に「10秒」で記録するだけで、あなたの技術が「5角形スキルチャート」として可視化され、次にやるべき課題が明確になります。総合格闘技(MMA)、ブラジリアン柔術(BJJ)、キックボクシング、レスリングなど、すべての格闘家の上達スピードを劇的に引き上げます。 【RollQuantの4つのコア機能】 1. 今日のコーチ(AIドリル提案&タイマー) ジムへ行く前や自主練の前に、今日の体調を1タップ。すると、今のあなたに最適な練習ドリルと、意識すべき「Good / Bad」のポイントをAIが自動提案します。内蔵されたラウンドタイマーを回せば、終了と同時に手入力ゼロで練習記録が完了します。 2. ヘトヘトな練習後でも続く「10秒記録」 ラウンドごとの細かい入力はもう必要ありません。「やったメニュー」と「スパー本数」をタップするだけ。たった10秒の記録で経験値(XP)が貯まり、毎日の努力が確実に積み上がります。 3. 何をすれば強くなるか分かる「スキル図鑑」 打撃・テイクダウン・壁際・寝技トップ・寝技ボトムの5カテゴリから、実戦で必須となる30種類以上のスキルと推奨ドリルを収録。ジムで習った技やYouTubeの教則動画のURLも「自分のオリジナル課題」として無制限に登録・管理できます。 4. 成長が目に見える「成長カルテ&動画分析」 モチベーションを削ぐ「勝率」グラフは廃止。あなたの習熟度を「5角形スキルレーダーチャート」で美しく可視化します。さらに、スパーリングの動画を保存し「01:15 ガードが下がった」のようにタイムスタンプ付きのメモを残せるため、自分の動きを客観視して弱点を最速で克服できます。 【RollQuant Pro(プレミアム機能)について】 基本機能はすべて「無料」で使い続けることができます。さらに本気で強くなりたい方向けに、圧倒的な上達環境を提供するProプランをご用意しています。 Proプラン限定特典: ・全30種以上の「Lv.2 実戦応用スキル&連携ドリル」の解放 ・オリジナル課題&教則動画リンクの「無制限登録」 ・5角形チャートから弱点をあぶり出す「AI弱点診断&強化処方箋」 ・スパー動画のクラウド保存 & タイムスタンプ振り返り ・タイマーの詳細カスタマイズ & 試合前のフル減量キャンプ管理 まずは「7日間の無料トライアル」で、専属のAIセコンドがいる新しい練習体験をお試しください。 ■ 注意事項 ・「RollQuant Pro」の定期購読は、お使いのApple IDアカウントを通じて請求されます。 ・現在の有効期間が終了する24時間前までに自動更新をオフにしない限り、自動的に更新されます。 --- ・プライバシーポリシー [https://docs.google.com/document/d/1cL_qJgs4l3yB0lXBncWK05rjSJjzABoyhrfmtE4Dyjs/edit?usp=sharing] ・利用規約 (標準Apple Terms of Use) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is in-app purchases: RollQuant at none against BJJCraft's 1. RollQuant also leads on ads (none vs shown). BJJCraft's advantage is update cadence (every 2 weeks vs monthly) and device support (3 vs 1). On price there is nothing between them.
