BJJ Logger

Free forever. No ads, no subscription, no BS. Just your training data. Sessions, subs, sparring, tracked and yours. Built by grapplers, for grapplers.

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.
