Two grapplers mid-roll in front of a crowd at a no-gi match

For grapplers

Every roll counts.

Session Zero is the training log, open-mat finder and team feed for BJJ, no-gi and wrestling. Built for the five minutes after class.

Log it

Every roll, drill and round in ten seconds, right after class.

Find the mat

Open mats and drop-ins near you, with who else is going.

Roll together

Follow your training partners and see who shows up.

Training log

Know what you worked on

Log the session type, the minutes and what clicked. Goals and streaks keep you honest; your notes stay yours.

Open mats & events

Never miss an open mat

Find open mats, seminars and comps around you. Sign up, see the roster and get a heads-up when plans change.

Your crew

Your gym, in your pocket

A feed of your training partners: who trained today, who is coming Saturday and who just got their stripe.

For gyms

Run your mat, not a spreadsheet.

Publish your class schedule and open mats, take bookings with a waitlist, and see who is training. Coaches get the roster; members get the reminder.

Get on the list.
