Key Differences

Marune's social feed is a real differentiator if community matters to your training: you can follow training partners, check in at your gym, track gi wear, and log progress across BJJ, judo, wrestling, Muay Thai, boxing, and more from one free app.

RollData logs at the round level: every round you record links a partner, a position, and the technique you hit or defended, building a position-to-technique map of your game over time. Marune keeps logging at the session level, without that structural connection.

RollData's free tier has no ads and no caps on core logging; Marune's free tier is ad-supported unless you buy a separate Ad-Free add-on. RollData also runs in any browser, so there's no app to install or update to keep logging.

The Verdict

Choose RollData if you want detailed tracking with features like round-by-round detail, position-technique mapping, partner tracking. Choose Marune if you prioritize social feed & community and multi-martial-art support. Both are solid options for BJJ practitioners, and the right choice depends on how you prefer to track your training.
