ROLLER — BJJ Gym & Tournaments

ROLLER is the app for jiu-jitsu athletes and their gyms.

[One-tap check-in] Tap once when you arrive, or scan the gym's QR on the wall. Your calendar fills up, your weekly streak shows, and gyms compete in a monthly attendance challenge with rankings.

[Belts and stripes] Record every belt and stripe from white belt on. See how many days since you started and how long you have worn your current belt, then share it as an image card. Keep a training log alongside.

[Tournaments in one place] Find a tournament and enter on the spot. Pay by card, mobile wallet or bank transfer, then follow brackets, match order, results and podium-point rankings. Overseas events take US dollars.

[Community] A global board and your gym's own board. Gym notices and open mat or seminar schedules appear as cards.

[Owner mode] Turn it on in account settings to manage members, attendance QR, dues records, timetable, promotions and monthly reports. Invite coaches to see the same screens. Dues go straight to the gym's own account.

[Organizers] Create a tournament, manage entries, generate brackets, run scoreboards and call the podium. Staff codes split referee and recorder roles.

[Parents] Check that your child made it to class today.

Available in Korean, English, Japanese and Chinese. Support: rollerbjj.com/support
