The membership that lives in their pocket.
Every Gym Stack 360 plan ships with a polished app your members will actually open: check in with a QR code, book classes in two taps, earn loyalty points, invite a friend — so your front desk can focus on people, not admin. It installs straight from the browser on iOS and Android: no app store, no download.

Check in and book in seconds.
Every tap your members don't need to make at the front desk is a minute your staff gets back. Members carry their personal QR and PIN, see live spot counts before they book, and when a full class opens up, the waitlist promotes them automatically — and the message lands in their app inbox and by SMS before they've noticed the spot.
- Personal QR + PIN for sub-second check-in at every location
- Class booking with live spot counts — no phone calls, no whiteboard
- Waitlist auto-promotion — the app inbox, SMS or email tells them the moment a spot opens

Habits that keep them paying.
Members who feel progress don't cancel. Loyalty points stack with every visit, booking and referral, tiers give them something to climb toward, and the app shows exactly how far the next one is. Reminders reach them where they actually read — SMS by default, email for the receipt.
- Loyalty points earned on visits, bookings and referrals
- Tiers and progress-to-next-tier — points balance and visit count, always in view
- Messages they actually get — class reminders, waitlist promotions and receipts by SMS or email
Growth built into the app.
Your happiest members are your cheapest acquisition channel. The app gives them a referral link with rewards on both sides, guest passes to bring a friend through the door, and enough self-service — freeze requests, their own bookings, their own payment history — that the front desk stops answering the same three questions.
- Referral program with rewards for referrer and friend alike
- Guest invites & passes that turn workout buddies into leads
- Freeze requests in the app — inside your quota and notice rules, approved from the admin

Member App capabilities, in full.
QR & PIN check-in
A personal QR code and backup PIN in every member's pocket — checked at the door, no card to forget.
Class booking & waitlists
Two-tap booking with live spot counts, and waitlists that promote members automatically when spots open.
Loyalty points & tiers
Points on every visit, booking and referral, tiers to climb, and a redeem screen that turns them into something real.
Referral program
Shareable referral links with rewards on both sides — your best members recruiting the next ones.
Guest invites
Guest passes members send from the app — workout buddies walk in as guests and leave as leads.
Their plan, on their screen
Current plan, membership status and full payment history — the three things they ring the front desk about.
In-app notification inbox
Booking confirmations, waitlist promotions, reminders, receipts and freeze decisions — all in one inbox in the app.
SMS, email & the app inbox
Bookings, reminders, receipts and freeze confirmations reach members by SMS or email, and every one is kept in their app inbox. WhatsApp is on the roadmap, not live yet.
Freeze requests
Members request a pause from the app, inside the quota and notice rules you set — you approve or decline in the admin.
Their data, their call
Members export a copy of their own data or request erasure from the app — GDPR handled without a support ticket.
Installs from the browser
An installable web app on iOS and Android — no app-store listing, no download, no update your members have to remember.
The member app is an installable web app — members add it from the browser on iOS or Android, and it updates itself. There is no native app and no app-store listing. It is English-only today; the admin app ships in English, Spanish, French and Portuguese.
