Stop stepping on the mat
without a plan.
OneMat is your Brazilian jiu-jitsu training companion built on motor learning science. It structures your rolls through one clear focus per session, a 30-second post-roll log, and 2–4 week technical cycles. Designed for class, open mat, and sparring when fatigue is high and attention is short.
We designed the training loop for real mat fatigue: one specific objective before you step on the mat, and one quick log while you are still in your gear. View focus → train with intent → 30s log → weekly review. No endless video walls to scroll — just a clear progressive line to target half guard, passing, or guard recovery, ensuring your training hours count.
OneMat is a dedicated training companion and logging app for Brazilian Jiu-Jitsu. It replaces aimless sparring with deliberate practice: one clear position, objective, and learning constraint per session, paired with 2–4 week technical blocks. We do not produce instructional videos; we structure your actual training on the mat.

Voices from
the mat
I used to hit the mat with no idea what to work on. Now I open the app, see my focus, and train with intent.
— Carlos M., Blue belt · Madrid
30 s
Post-roll logging that respects mat fatigue.
The 30-second log is everything. I'm dead after rolling — I'm not filling out a journal.
— Andrés R., White belt · Mexico City
Two cycles in and I noticed I was making fewer mistakes from half guard. The data doesn't lie.

Guides & comparisons
Dig deeper before you download
Not every BJJ app does the same job. Some are for writing notes, some for watching technique, and some for keeping a line of work you can hold across tired weeks. OneMat is that last type: one clear direction for the day, a quick log after you roll, and 2–4 week blocks you can come back to. The guides below walk through how that shows up in practice, how we line up next to other apps, and when an open-mat plan actually clicks. The comparison pages are dated and plain about trade-offs so you are not choosing from marketing fluff alone.
What each tab does on a real night
A walk through Today, Log, Progress, and Library — how they connect when you are tired, rushed, or between rounds.
Open pageTypes of BJJ apps — and where we fit
Journals, video, S&C, and structured mat companions: what each is for, and when OneMat makes sense for you.
Open pageThe training log that powers your focus
Why chips, counters, and a short readback change what you do next session, not what you type in a notes field.
Open pageAI BJJ coach after the roll
How I turn a fast log into next-session direction without generic hype — grounded in what you recorded.
Open pageOn the mat (open mat focus)
A practical use case: from walking in without a plan to a checklist and one clear objective for the night.
Open pageOneMat next to other apps you know
Each page shows when it was last updated. If you are already thinking about a specific app, these lay out who optimizes for what so you are comparing apples to apples, not adjectives.
Why you can trust what we publish
Every app comparison and training guide here comes from people who still train. We do not accept paid placements or sponsored rankings. If we recommend something, we used it on the mat and judged whether it actually helps serious practitioners.
We are active purple, brown, and black belts based in Spain and France. We train daily, test OneMat in our own sessions, and write from that experience—not from anonymous writers or stock profiles.
