Class booking and memberships for gyms
Website with class calendar, card subscriptions and punch cards — built specifically for gyms, yoga and pilates studios.
Your site · live in minutes
No credit card
GDPR compliant
EU-hosted
Support in your language
Built for classes and members
Six features that replace Mindbody at a fraction of the price.
Class booking with capacity
Define class types (yoga, HIIT, pilates), max capacity and waitlist. Members book themselves.
Subscription by card
Monthly or annual membership charged automatically to the member's card.
Punch cards and drop-in
Sell 10-class punch cards or drop-in passes. Balance deducts automatically on booking.
Automatic reminders against empty spots
Every class booking triggers a confirmation and a reminder before the class. Fewer no-shows mean full classes and a waitlist that has time to move up — an empty spot in a class can't be sold again afterwards.
Class schedule with instructors and rooms
Build your weekly schedule with instructors, class types and rooms, and let the AI suggest recurrences automatically. Members always see an up-to-date calendar on your own site — on both mobile and desktop.
Commission-free and EU-built
You pay one fixed, low monthly price and keep the full amount for every membership, punch and drop-in — we take no commission per booking. The platform is built in the EU with support in your language, card payments and EU data processing by default.
The challenge for gyms and studios
Most gyms, yoga and pilates studios end up with a patchwork of tools: a website in one place, a class-booking system in another, a separate tool for memberships and maybe an SMS service on top. Each part costs money, needs maintaining and rarely talks to the others. At the same time, every empty spot in a class is lost revenue that can't be resold — no-shows and forgotten cancellations eat straight into the bottom line while the waitlist never moves up in time. Many international platforms charge in dollars, lack local payment options and offer only English support, so members face a payment method they don't recognise. The result is more subscriptions, manual handling of punch cards and memberships, and a schedule that never quite fills up.

Why gyms and studios choose Sitenyx
Website, schedule and membership in one
No more paying for and maintaining a class-booking system on top of your website. Members book classes, buy punch cards and sign up for memberships directly on your own studio site — one subscription, one login, one place to keep updated.
Commission-free — you keep the full amount
We take no percentage of your memberships, punches or drop-ins. You pay one fixed, low monthly price and keep the full income for every member and every booking, unlike platforms that take a fee per transaction.
Full classes and fewer no-shows
Class booking with capacity and waitlist ensures a freed-up spot is quickly filled again. Automatic confirmations and reminders before class get members to show up — so fewer spots go to waste and the waitlist has time to move up.
Recurring income on autopilot
Membership subscriptions are charged automatically to the member's card, so income comes in by itself. If you want dunning on failed cards, a schedule with waitlist and PT programmes all in one place, we point you on to our Memberships solution.
EU-built with card payments and EU data
The platform is built in the EU with card payments and EU data processing by default. Your members pay for memberships and punch cards in a way they know — no currency conversion, and you get support in your language when you need it.

A typical setup means a separate website, class-booking system, membership tool and SMS service, each on its own. Sitenyx brings class booking, memberships and punch cards together in one place.
| Typical setup | Sitenyx | |
|---|---|---|
| Number of tools | Separate website, class-booking system, membership tool and SMS service | Everything in one — website, schedule, membership, punch cards and reminders |
| Pricing model | Multiple subscriptions, and some platforms take a fee per transaction | One fixed subscription, commission-free — Pro DKK 249 / Premium DKK 583/mo (billed annually) |
| Class booking | Lives in a separate booking tool alongside the website | Class calendar with capacity and waitlist directly on your own site, 24/7 |
| Membership and payment | Manual invoicing or an international platform in dollars with no automatic card billing | Automatic membership subscription charged to the member's card, monthly or annual |
| Punch cards and drop-in | Tracked by hand or needs an extra add-on with its own fee | Built-in punch cards and drop-in, balance deducted automatically on booking |
| Ownership and support | Member data may sit with a foreign platform; support often in English | You own the member relationship; EU-built with support in your language and EU data |

Questions about booking systems for gyms
What business owners ask most before getting started.
Can I have both the gym's website and class booking in one place?
Yes. You get both a professional website and a complete class-booking system in the same tool — members book classes, buy punch cards and take out subscriptions directly on your own site.
How much does a booking system for a gym cost?
You can start completely free with a website, class calendar and online booking. Pro is DKK 249/mo (billed annually) and adds punch cards, membership subscriptions and card payments. You can cancel anytime — an annual plan runs to the end of the period you've paid for.
How does class booking with capacity and waitlist work?
You define class types (HIIT, yoga, pilates), maximum capacity and a waitlist. Members book themselves, and when someone cancels the waitlist moves up automatically — so your classes stay full.
Can I charge memberships automatically by card?
Yes. You offer monthly or annual memberships charged automatically to the member's card. Punch cards and drop-in tickets are also sold on the site, and the balance is deducted automatically at booking.
Does the system send reminders so members show up?
Yes. Every class booking triggers an automatic confirmation and a reminder before the class, so fewer spots go to waste and the waitlist can move up in good time.
Do I pay commission per booking?
No. You pay a fixed low monthly price and keep the full amount of every membership, pass and drop-in. We take no commission on your bookings.
How fast is my site ready, and does it work on mobile?
Our AI builds a finished gym website with a class calendar in under 60 seconds, and you can go live the same day. Both the class calendar and the booking are fully mobile-optimised.
