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.
