Industry: fitness

Websites for gyms: class schedule, online memberships and class booking, from €600

A schedule people can read on a phone, plans they can buy in a minute and checkout terms that say what the member agrees to.

A gym site that sells memberships and fills classes

We build websites for gyms and fitness studios: a class schedule, online membership purchase, trainer profiles, class booking and card payments. A presentation site with schedule, prices and a trial request usually costs €600–1,500. Online membership sales and class booking are custom-coded and start at €2,500. A shop with products and complex recurring billing moves into the e-commerce band from €4,000. A static 1–2 page site is €150–350. We work remotely and charge the same anywhere in Romania.

A schedule people can read on a phone

A timetable needs day, time, class, trainer, room, level and places left. Visitors filter by day and class type, and a cancelled class disappears from the page within seconds. An add-to-calendar button turns a glance into a plan. A photo of the timetable pinned on a page does none of this.

Selling memberships online

List the plans (day pass, monthly, 3, 6 or 12 months, student, couples) and show the price, the duration, the renewal rule and the cancellation rule before the pay button. Ordinance 34/2014 gives consumers 14 days to withdraw from a distance contract (article 9). Article 16 excludes leisure services from that right when the contract sets a specific date or period of performance. Whether an open-ended membership fits that exception is a legal question, so do not assume it: have your checkout terms reviewed by a lawyer or ask the consumer authority. The pay button must also say that the order creates an obligation to pay (article 8). From 19 June 2026, EU Directive 2023/2673 adds a withdrawal function to online contracts that carry a right of withdrawal, so check how Romania applies it.

Health data stays out of the website

A readiness questionnaire reveals health information, which GDPR article 9 treats as a special category: processing is prohibited unless an exception applies, such as explicit consent. Keep medical questions out of public forms. If you need them, collect them at the front desk or inside a protected account, and only what the training requires.

Trainers and their qualifications

Show names, photos, specialties and only the qualifications each coach holds. A statute approved by Order 683/2025 says organised sports training is provided by people attested by a diploma or qualification certificate. Whether it applies to a given coach in your gym is something to confirm with the sports authority. The site should claim nothing beyond the certificates.

Class booking and payments

Capacity, a waiting list, a late-cancellation rule and a no-show rule decide whether booking helps or irritates. Card payments go through a payment provider, whose fees you check yourself. Recurring renewals need the provider's support for strong customer authentication, and we test a real payment before opening.

App or website?

The website is what Google shows to someone searching for a gym nearby. A web app can be installed to the home screen and works like an app without a store, as Google's web.dev explains. A native app costs more and needs store updates, so it pays off when members book several times a week and someone maintains it. We start with the site and look at usage.

Your existing gym software

Many gyms already run membership software with access control. The site can link to or embed its booking pages instead of rebuilding them, and where the software has an API we can show the live schedule. We check before quoting. Billing and member accounts are what move the price. Read our cost guide or book a free call.

What the site includes

Six things a gym site needs

Built for members who decide on a phone and for owners who want fewer calls.

  • Class schedule

    Day, time, class, trainer, level and places left, with filters and an add-to-calendar button.

  • Online membership purchase

    Plans with price, duration, renewal and cancellation shown before the pay button.

  • Trainer profiles

    Names, photos, specialties and only the qualifications each coach holds.

  • Class booking

    Capacity, a waiting list and clear late-cancellation and no-show rules.

  • Payments and data care

    Card payments through a provider, and health questions kept off public forms.

  • Installable web app

    The site can be added to the home screen, so many gyms do not need a store app to start.

How it works

How a gym site project runs

  1. 1

    Call: classes, plans, software

    You describe the classes, the plans you sell and any membership or access software you already run.

  2. 2

    Terms and checkout design

    We write the plan descriptions and checkout wording, and flag the withdrawal question for your lawyer to review.

  3. 3

    Build schedule, plans and booking

    We build the schedule and the purchase or booking flow, or connect to your existing booking pages.

  4. 4

    Real payment test and launch

    We run a real card payment before opening, then hand over how to edit the timetable and plans.

Related work

We have no client in fitness yet, so there is no gym site to show you. The nearest work is booking. The RecMed clinic is a concept for a medical recovery clinic, with a consultation booking flow, team profiles, a blog and light and dark themes. This website has live booking on Google Calendar, covered in our booking guide. Both handle appointments, not classes with limited places or recurring payments, so a class-booking flow would be new work that we scope with you. Both pages are labelled as what they are.

FAQ

Questions, answered

How much does a gym website cost?

A static 1–2 page site is €150–350. A presentation site with an editable schedule, plans, trainer profiles and a trial request is usually €600–1,500. Online memberships and class booking are custom-coded from €2,500, and a shop or complex recurring billing moves into the e-commerce band from €4,000.

Can members buy and pay for memberships online?

Yes, with card payments through a payment provider. The checkout shows price, duration, renewal and cancellation before the pay button, and the button says the order creates an obligation to pay. Provider fees are yours to check. We test a real payment before opening the shop.

Do online memberships carry a 14-day withdrawal right?

Ordinance 34/2014 gives 14 days for distance contracts but excludes leisure services with a specific date or period of performance. Whether an open-ended gym membership qualifies is unclear to us, so we do not decide it. Ask a lawyer or the consumer authority to review your terms before launch.

Can the site take class bookings with limited places?

Yes. A custom flow can hold capacity per class, a waiting list, a late-cancellation rule and a no-show rule. If your gym software already offers booking pages, the site can link or embed them instead. We check what your software allows before quoting and say so in writing.

Should I get an app or a website?

Start with the website: Google shows it to people searching for a gym nearby, and it can be installed to the home screen. A native app costs more and needs store updates, so it is worth it when members book several times a week and someone maintains it.

Can I collect health questionnaires on the site?

We advise against it. Health information is a special category under GDPR article 9, and processing is prohibited unless an exception applies, such as explicit consent. Collect only what training requires, at the front desk or inside a protected account, and keep it out of public forms.

Can the site connect to our existing gym software?

Sometimes. Where the software offers an API or booking pages we can show the live schedule or link to them. Where it offers neither, we say so in writing before quoting. We do not promise an integration until we have checked what your provider allows.
