BJJ Logger: Jiu Jitsu Journal

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. • iOS and Web — 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.
