Class booking and memberships for gyms
Website with class calendar, MobilePay subscriptions and punch cards — built specifically for gyms, yoga and pilates studios.
Built for classes and members
Three 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 via MobilePay
Monthly or annual membership charged automatically via MobilePay Subscriptions.
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 Danish-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 Denmark with Danish language, MobilePay and EU data processing by default.
The challenge for Danish 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 MobilePay 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 via MobilePay Subscriptions, 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.
Danish-built with MobilePay and EU data
The platform is built in Denmark with Danish language, MobilePay 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 Danish support when you need it.
