自分なりの学びをメモとして残すことに特化した柔術専用ノートです。

スパーの本数、練習の数、頑張った記録として残せるところが嬉しいです。

頭の整理に良いです

趣味で柔術してますが、動きが止まるところがあり、フローチャートに起こすことでどんなスキルが不足しているか見える化できました。とても良いアプリです。フローチャートの全体図を確認している時、誤ってフローを動かしてしまうことが良くあるので、編集ロックモードの追加をしてほしいです。フローのタイトル名の文字制限も増やしてくれると文章で管理しやすくなるので改善してほしいです！

I have found zero bugs in this app. You can keep memos, set daily and monthly goals. Track your rolls. Add Videos added with TIME Stamps. Flow chart features to make your own charts. Video groups so you can focus on a topic and more… I absolutely love this app. I am wishing this team the best!

This is a great tool for organizing your JJ progression and tracking the thousands of videos that I view, and then forget about! I am enjoying it.

有能！また一つ強くなれる

とても使いやすく、これでまた練習が楽しくなると思いました、
今まで個人で煩雑に管理していた、メモや動画をわかりやすくまとめることができる。フローチャートが特にありがたく、練習で実践したいこと、うまくいかなかった場合等のなんとなく頭の中で整理されている内容を可視化できる！
