Honest comparison
OneMat vs BJJ Notes — journal or structured training?
BJJ Notes is a solid journal app: you record what happened and keep a personal log. OneMat takes a different approach — your log feeds your next focus, and 2–4 week cycles keep progress compounding. Here's an honest look at both.
Quick answer
BJJ Notes shines as a flexible BJJ journal: you capture techniques and session notes in your own words. OneMat is built for open mat structure—one focus per roll, ~30-second logging, and 2–4 week cycles so your log informs the next objective. Choose BJJ Notes for memory; choose OneMat when you want deliberate, compounding progression.

Key differences
Three lenses. Same mat.
Active Technical Direction vs. Passive Note Archiving
BJJ Notes acts as a passive digital notebook where you log class details and sparring notes for manual review. OneMat turns logging into a closed feedback loop: the chips and success rates you record in under 30 seconds automatically calculate and suggest the exact position, objective, and learning constraint for your next session on the mat.
Constraint-Led Training vs. Open-Ended Journaling
BJJ Notes is completely open-ended—you can write paragraphs of text that can become hard to analyze or review when tired. OneMat is highly opinionated and structured, limiting your daily focus to a single position, a clear victory condition, and a specific learning constraint (e.g. no collar grips to force underhooks) to accelerate motor skill acquisition.
Compounding Technical Cycles vs. Session-by-Session Logging
BJJ Notes tracks sessions chronologically without grouping them by focus area. OneMat organizes your training into 2–4 week focus cycles. This allows you to stick to one position (like half guard or side control) over consecutive sessions, tracking your technical adherence and success rates until they consolidate into muscle memory.
Which one should you pick?
Choose BJJ Notes if
- You want a simple, flexible journal for personal notes
- You prefer free-text logging over structured inputs
- You don't need next-session direction — you already plan your own training
Choose OneMat if
- You want your log to feed your next focus automatically
- You train open mat and need a clear direction each session
- You want progress cycles, not just session records
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.
