What you can track
A diary that speaks jiu-jitsu.
Built around the way you actually train, from the first warm up to the day you tie on a new belt.

- Guard Passing
- Mount

- Submissions
- Escapes
- Sweeps
- Transitions
Goal setting
Aim, then achieve.
Pick a preset like guard retention or competition prep, or write your own. Active and achieved goals stay separate, and marking one done records the date for you.
Accounts & profiles
One account, every athlete.
Run several profiles under one login, so a parent can track a child alongside their own training. When a young athlete is ready, graduate their profile into an account of their own, history and all.
Home overview
Everything at a glance.
Your home screen shows recent sessions, a streak signal that tracks your consistency, and the single most useful thing to work on next.
AI coaching
Advice that reads your diary.
It works from what you actually log, not generic tips. One top call sits on your home screen. The full list lives in Advice.
Coverage gap
You have logged Guard eleven times this month, and Takedowns zero. Add a standing round to round out your game.
Reads your technique history by category
Consistency nudge
Three sessions last week, none so far this one. A short open mat keeps your streak alive.
