About this app

Ossify is the home for Brazilian Jiu-Jitsu.

Built for the people who actually train — athletes, coaches, gym owners — Ossify connects every mat, every round, and every promotion in one place.

For athletes — free, forever.
• Find a gym anywhere in the world on the discovery map
• Drop in to listed gyms while traveling, with one tap
• Track every class, every round, every belt promotion
• See your training history, mat time, and progression at a glance
• Join your home gym, view the schedule, and check in to class
• Log a session you forgot to check into, up to a week later
• Get announcements from your coaches

For gym owners — everything, free. Every gym gets a page on the discovery map — and the full toolkit to run it:
• Member roster with belt ranks, attendance, and contact info
• Class schedule with capacity, instructors, and check-ins
• Drop-in approvals from visiting practitioners
• Belt promotion tracking and history
• Gym announcements pushed to every member
• Membership start/end dates, with freeze and resume

Everything in Ossify is free — there are no paid tiers, no subscriptions, and nothing to buy.
Designed for travel. Whether you’re rolling in São Paulo, Tokyo, or your home academy on a Tuesday night, Ossify keeps your training in one feed. One platform. Every mat.
Privacy first. Email-only sign-in. No password, no social tracking. Your training history is yours.
Pricing Ossify is free to download and use, for athletes and for gyms. There are no in-app purchases.
