GymOS — Operating System for Gyms
Run your gym.Not your software.
GymOS connects memberships, payments, classes, check-in, and daily operations into one platform — built around how a gym actually runs, not around a generic booking calendar.
In production
Running a real gym, right now.
GymOS isn't a concept. It's the platform ARES Training Club operates on today — members, payments, and daily front-desk work, running through the same system described on this page.
- Live production deployment
- Web admin + native mobile app
- Stripe-powered billing
- Distributed via App Store & Google Play
- White-label infrastructure
One system
Everything connected.
The value isn't any single screen — it's that members, payments, classes, check-in, front desk, and management all read from the same source of truth.
- Members
- Registration, authentication, and profiles in one directory.
- Payments
- Stripe subscriptions, enrollment fees, and cash sales reconciled together.
- Classes
- Schedules, capacity, and waitlists tied directly to membership status.
- Check-in
- QR access confirms an active membership in real time, at the door.
- Front desk
- Every walk-in, sale, and verification logged where staff can see it.
- Management
- Owners see the business as it actually runs — not a delayed summary.
Executive visibility
Know how the gym is doing — today, not next month.
The executive dashboard surfaces what an owner actually checks: today's activity, the month so far, 30-day direction, and anything that needs attention.
Illustrative dashboard — figures shown are sample data, not a customer's results.
Front desk
Built for the front desk, not around it.
The workflow staff actually run, start to finish — designed to be fast during the moments the front desk is busiest.
01
Find or register a member
Look up an existing profile or register a new one in seconds.
02
Sell a membership
Handle walk-ins and new sign-ups without leaving the counter.
03
Accept payment
Cash or Stripe — both flow into the same record.
04
Verify and go
Confirm membership status instantly and send the member on their way.
Member experience
A gym app that actually carries the gym's brand.
Members get a native mobile app under the gym's own name and identity — account, membership, classes, and check-in, not a shared marketplace app.
Account
Profile and membership in one place.
Membership
Status, plan, and payment history.
Classes
Browse, book, and join waitlists.
QR check-in
Contactless access at the door.
Waiver
Accept and sign on first use.
Memberships & billing
Revenue, handled properly.
Stripe subscriptions and cash sales resolve into the same billing record, so the front desk and the owner are always looking at the same numbers.
Stripe subscriptions
Recurring membership billing, handled by Stripe.
Enrollment fees
One-time fees applied at sign-up, tracked alongside recurring billing.
Promotional campaigns
Founders pricing and promotional offers, run through the same system.
Payment status
See who's current, who's past due, at a glance.
Billing center
One place to administer billing across every member.
Membership verification
Confirm active status before a member walks onto the floor.
Classes & access
A schedule members can trust.
One official schedule, with capacity and waitlists enforced automatically — and access at the door tied to the same membership record.
Official schedule
A single class schedule staff and members both see.
Capacity & waitlists
Classes fill and waitlist automatically once they're full.
QR check-in
The same check-in flow used for general gym access.
Role-aware access
What a staff member can see and do depends on their role.
White label
The gym's brand. Not FraterUnion's.
Every implementation is configured and deployed as a branded product — the gym's name, identity, and app listing across mobile and admin. This is a deployment FraterUnion configures for each gym, not a self-serve toggle.
- Branded mobile app, listed under the gym's own identity
- Branded admin web application
- Distributed through the App Store and Google Play
- Delivered as OTA updates once live, without a resubmission for every change
One platform. Every gym's own identity.
Built for the whole team
Everyone sees exactly what their role needs.
Access is shaped around each job on the floor — so staff move faster and owners keep control, without a shared login covering every permission.
Owner
Full visibility into the business, everywhere.
Admin
Runs day-to-day configuration and operations.
Front Desk
Fast access to sales, check-in, and members.
Staff
The operational tools their work actually needs.
Instructor
Class rosters and schedules, nothing extra.
Member
Their account, membership, and classes — in the app.
