BJJ Logger

Every roll. Every tap. Tracked.
The training log built for jiu-jitsu. Sessions, techniques, submissions, sparring — logged, tracked, brutalized into data. So you can see the work.

WHAT IT DOES
• SESSIONS — Log every class. Type, duration, techniques drilled, sparring notes. All in 30 seconds.
• TECHNIQUES — Build your move library. Rate proficiency 1–5. Watch the gaps fill in over months.
• SUBMISSIONS — Track every sub you've landed and every one you've caught. Build your finishing game.
• SPARRING — Roll log: partners, outcomes, what worked. See your matchups against every belt color.
• NOTES — The mat journal. Coach details, drilling reminders, mental game work — searchable, dated.
• DASHBOARD — Heatmap. Streak. Recent sessions. Everything at a glance.

WHO IT'S FOR
White belts through black belts. Hobbyists through competitors. If you train and want to see the shape of it, this is the log.

WHY
• Free. No ads. No subscription.
• Belt-aware UI (white → black).
• Heatmap and streak tracking.
• Web, iOS, and Android — your data syncs across all of them.
• Your data stays yours.

Built because we got tired of writing notes in 4 different apps. Every feature exists because you actually use it on the mat — or right after.
Stop guessing. Start tracking.
