Jiu Jitsu Reference

Track what lands, slips, and catches you. Build a clearer picture of your jiu-jitsu game after every roll.

Jiu Jitsu Reference is a knowledge journal for Brazilian jiu-jitsu practitioners who want to understand their game.

Log the techniques, positions, systems, and submissions you hit, miss, or concede against resisting training partners. The app turns those quick logs into a personal view of what is active, what is slipping, what keeps catching you, and what deserves more attention.

Built for serious hobbyists and competitors who reflect on their training, Jiu Jitsu Reference focuses on knowledge instead of workout volume. No rounds, calories, attendance charts, or social feed. Just fast logging and useful patterns from your own mat time.

Key features:

• Fast live jiu-jitsu logging
• Curated technique and position reference
• Personal knowledge nodes for your own game
• Partner-specific patterns

Use it after class, after open mat, or between rounds to preserve what actually happened while it is still fresh.
