FAQ.

Everything you need to know before stepping on the mat.

An app for BJJ practitioners that lets you compete in ranked matches anytime, at any partner gym, logging results through an ELO system.

Both regular competitors and practitioners who have never competed or only do so occasionally. The ELO system enables balanced, safe matchups.

Submission only, time cap set by the gym or both parties. No official referees: based on honesty and respect, reinforced by the Honor System. If time runs out without submission, it's a draw.

A scoring system that adjusts your level by results and opponent level. Beating a strong rival climbs you fast; losing to someone below penalizes.

Yes. You can create private duels and invite users directly or by link — ideal for gym partners.

Honor System. Late cancels or no-shows have their honor reduced, visible on their profile. The gym validates the no-show, your share is refunded, and you can still enjoy the mat time as open mat.

Free basic version: rankings, profile and +10 free Fast Duels per month. Premium version: unlimited Fast Duels, advanced stats, more visibility.

Designed for BJJ practitioners in approved gyms. Each user competes under their own responsibility and accepts the terms before each duel.
