Memberships, classes, PRs — the gym your members actually keep.
Members watch their PRs, streaks, and class history stack up on their IOX passport — the kind of progress that keeps them paying. You run membership billing, class schedules, check-in, PT bookings, and challenge engines.
Purpose-built for gyms & fitness.
Everything you need to run gyms & fitness — booking, payments, ops, and the social layer that compounds into a passport for every customer.
Membership Management
Flexible plans, family accounts, freezes, and automated billing with Stripe-powered recurring payments.
Class Scheduling
Group fitness timetables with instructor assignments, capacity limits, and waitlist management.
Workout Tracking
Members log workouts, track PRs, and follow training programs — all tied to their IOX profile.
Challenge & Goal Engine
Run gym-wide challenges, streak tracking, and milestone rewards to keep members engaged.
Member Check-In
QR code, key fob, or app-based check-in with access control and real-time occupancy tracking.
Personal Training
PT session booking, trainer availability, package management, and automated session reminders.
What sets it apart.
The features built specifically for gyms & fitness — the kind of operator-specific tooling generic SaaS can’t match.
Retention Analytics
Identify at-risk members with attendance patterns, engagement scoring, and automated re-engagement campaigns.
Auto-Renew & Upsell
Smart renewal flows with upgrade prompts, add-on services, and win-back offers for lapsed members.
Community & Social
In-app social features, buddy workouts, and member leaderboards that build community and reduce churn.
No monthly fees. No setup costs. The whole platform.
You don’t pay us. IOX Grit is free for the venue. A 6% service fee paid by your customer at checkout funds the entire platform. You keep 100% of your ticket price. Every feature ships out of the box — no premium tiers, no gated upgrades. Funds settle directly to your Stripe account.
The first operator on each spoke gets 5% instead of 6% — forever, by invitation. Standard plan is 6%. See operator details.
Cross-platform identity
Customers use one IOX account across every spoke. No duplicate signups, no lost booking history. The day you go live on IOX, every existing IOX Adventurer in your area is already reachable.
Unified analytics
Bookings, revenue, customer retention, and per-experience performance — every dashboard you need in one place. Export to CSV, JSON, or PDF whenever you want a copy.
Production-grade security
PCI-compliant payments through Stripe, encrypted at rest and in transit, tenant-scoped row-level security in Postgres, and MFA on staff access to production. Security documentation available on request — happy to walk through it.
