GymOS — The operating system for membership-based fitness studios

Run your gym.Not your software.

Membership, entitlement, waiver, schedule, and software check-in connect through one Member Operational Record — so the studio knows who can participate, and why.

Resolve a member

Replacement platform. White-label. In production.

Signature

Resolve the Member

Independent operational states stay independent. GymOS resolves them into one participation decision — then records the visit.

Membership is not payment.Payment is not entitlement.Booking is not attendance.

Illustrative resolve for Jordan Lee at Northline Training. Membership, payment, entitlement, waiver, booking, and Open Gym remain independent. Outcome: CLEARED for Strength 18:00. Attendance recorded as CLASS via QR. Exception: payment past due with valid entitlement clears class and surfaces billing attention.

System of management

What needs attention —today.

Operating Day compresses arrivals, capacity, eligibility, billing attention, and collection into one control surface — not a vanity dashboard.
