Who we are & why we build

Built for the serious BJJ training loop.

OneMat was created by a small team of active Brazilian Jiu-Jitsu practitioners who were tired of stepping onto the mat without a clear focus, and equally tired of complex journaling apps that feel like homework after a grueling session.

Our Story

We love jiu-jitsu, but we noticed a common plateau: most practitioners show up to open mat or sparring sessions with no plan. They roll hard, repeat the same subconscious mistakes, and leave their progression to chance. When they try to log their sessions, they are faced with heavy note-taking templates that do not respect post-roll fatigue.

OneMat is our answer. It is not an educational course library or a video database. It is a dedicated BJJ tracking companion designed for the mat: one clear technical focus before you train, a 30-second log right after, and 2-4 week cycles to let your progression compound.

How we train

The Deliberate Practice Methodology

Our app is built on established motor learning science. According to research on deliberate practice (Ericsson, 2016; Schmidt & Lee, 2019), skill acquisition requires a specific focus, immediate feedback, and repetition under constraints. OneMat applies this directly to BJJ: rather than collecting dozens of disconnected techniques, you focus on one position with progressive objectives and specific rules that force your brain to learn.

By tracking your cycle adherence over 2-4 weeks, the app makes your technical progress visible without relying on vanity metrics or empty gaming streaks. Stats are used for one purpose: to give you concrete direction for your next roll.

On the mat

How we use OneMat ourselves

Saturday open mat

One focus for all rounds — e.g. knee shield retention with a no-grip escape constraint. Log after, check cycle adherence before the next week.

Weeknight class follow-up

Coach showed a pass in class; Tonight tab connects that theme to one objective under a tighter constraint for live rounds.

Between competitions

3-week cycle on the position that cost the most points last comp — not random technique roulette.

The OneMat Team

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.

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.

Comparisons

How we evaluate BJJ apps

We publish honest comparisons written by active grapplers — no paid placements. Start with the hub, then read side-by-side pages when you are choosing a journal or training companion.
