You already know the problem

The dojo is open two days a week

But you want to train every day.

You forget the kata order

No one is there to correct you or remind you what comes next.

You can't see your progress

There's no record of what you practiced or how consistent you were.

What Joryu gives you

Streaks that earn you belts

Log every session and keep your streak alive. Everyone starts with the white belt — 365 days of practice earns the black belt.

These belts track practice consistency — they are not an official rank or grade awarded by a teacher or federation.

Kata & technique library

Every kata and technique for your discipline, with clear step descriptions and reference videos.

A public profile that tracks your practice

A practice heatmap, your streak, and a profile you can share — opt-in and public, like a GitHub for martial artists.

Your streak, your heatmap, one glance

Log a session in seconds. Your streak, this week's minutes, a GitHub-style activity heatmap, and belt progress — all on one screen, updated the moment you log.

A real reference library, not a placeholder

Kata and technique breakdowns for every discipline we cover — verified against standard curricula, not guessed. Reference videos are added as they're filmed; the written description is always there in the meantime.

A public profile — like a GitHub for martial artists

Opt in, and your streak, belts, and activity heatmap become a shareable page. Follow other practitioners, see the week's leaders per discipline, and turn consistency into something visible.

Installable: add it to your home screen and use it like a native app.
