BJJ Tracker is a free training log for Brazilian Jiu-Jitsu. It works in your browser and as an Android app, and your data stays yours.
Every time you finish a roll with a submission or get tapped, add it in a few taps: the technique, your training partner, their belt, and whether it was Gi or No-Gi. Forgot to log something last week? Pick the date and backfill it.
Submissions and taps are tracked separately, so you can see what you finish and what finishes you.
Type the technique the way you would say it at the gym, like "triangle from guard" or "Kimura", and BJJ Tracker groups it into a category such as Triangle Choke, Armbar, Shoulder Lock, or Guillotine. Your By Type view then shows which techniques you land most and against which belts.
The Trends tab charts submissions and taps by week over any range from one week to a year, along with your submission ratio, your current streak without a tap, and your best week.
Filter everything by Gi or No-Gi to see how your game differs between the two.
Pick any training partner to see how your rolls against them have gone over time. Only partners you have actually logged against in the selected range show up, so the list stays short and relevant.
Create a private group, share the invite code, and see who has the most submissions this week or the longest streak without a tap. Only counts are shared with your group. Your technique log and training partners stay private.
Already keep a spreadsheet? Import a CSV or Excel file with your technique, partner, belt, date, and Gi or No-Gi. Rows without a date are saved as undated, so they never distort your trends, and you can add dates later.
