01 / 03Less desk work

Admin on autopilot.

Payments, attendance and promotions run themselves. You teach.

Cut the manual work

Payments collect themselves.

  • One tap confirms a class and registers everyone enrolled
  • One ledger for card and cash, exportable to Excel
  • Membership status computed from real payments

Made for jiu-jitsu

Generic gym software doesn't know what a stripe is.

Ossly counts every class toward the next stripe. Students see where they are. You see who's ready.

Kids belts too
White to green, tracked the same way

Belt system

Promotions in one tap, certificates included.

White to black, four stripes each. The full promotion history of every student, kept clean.

  • Exam-ready flags show who hit the class count
  • Stripe or belt awarded from the student's page
  • PDF certificates students save straight to their phone

Your techniques in their pockets.

Yours, or everyone's

  • Your own techniques ordered the way you teach them
  • Or the shared library built together by academies on Ossly
  • By type or by belt takedowns, passes, sweeps, submissions

03 / 03Grow faster

Get more students.

Your members bring their friends, and joining takes two minutes: from a link, a code or a QR at the desk.

Grow the academy

Your students are your sales team.

Every student gets a referral code and a link to share. A friend joins with it, the referrer's subscription gets longer. You reward a member only once they have actually brought you one.

  • A code or a link shared on the mats or in a chat
  • Free days on their subscription: 3 per monthly friend, 40 per yearly
  • Rewarded automatically on the referrer's next payment

Direct invites

Joining takes a link, not a clipboard.

Your academy runs at its own address, and anyone can sign themselves up there. Put the link in your Instagram bio, drop it in a WhatsApp chat, hang it as a QR code at the front desk.

  • One link, yours wherever new students find you
  • Walk-ins scan and sign up before they have even left the gym
  • No re-typing they land in your member list, ready for their first check-in

Caramba, the academy pretty much runs itself now. And the students are hooked to the app! Checking who is ahead in the ranking, studying techniques on and off the mat. Really made our BJJ family stronger, OSS.
