The software for CrossFit boxes and functional fitness gyms in Belgium. Health insurance forms, the quarterly VAT and your coaches' hours get ready on their own. You check, you approve, and your Sunday evening stays free.
Book a callWhat your members get
30-day trial, no bank card needed. Then you pick your plan or you stop: nothing is charged without your consent. The screenshots are in French; the app itself works in English, Dutch and French.
Most Belgian health insurers refund part of the gym membership every year. The member picks their insurer in the app and receives the official form already filled in, with your signature and stamp. All they have to do is send it.
You: not a single form to fill in by hand.
Them: a real reason to stay with you.
Designed with a physiotherapist. The member reports pain in three taps: where, which side, how strong. Before class, the coach gets a clear brief: who is in pain, what to adapt, who is back from injury, who is new, who can beat a record.
Every reported pain reaches the coach before class.
Your members' payments are already in the app. Add your expenses with a photo of the receipt: VAT is sorted box by box, loans and investments depreciate on their own. At the end of the quarter, a complete file goes to your accountant.
Your accountant gets a complete file, not a box of receipts.
Is your week in a document, a WhatsApp, a spreadsheet? Copy, paste: the app recognises the days, the blocks and the workouts, and puts them in your schedule. Your members see the session of the day, log their score, and the gym screen shows the live leaderboard.
Your week of programming published without retyping anything.
Strength, weightlifting, gymnastics, endurance, speed: every score counts. Athletes see where they progress and what to work on. The coach knows which version of the workout to offer to whom.
Every member knows what to work on, and so does their coach.
Classes taught, appointments, extras: the month fills itself. You approve, you export for your payroll office. A coach without a confirmed Dimona cannot open their space: nothing gets forgotten. Contracts are signed with a finger in the app.
No more paper timesheets or forgotten Dimonas.
Book, pay, log their score, see their progress, get their health insurance refund, message their coach.
Member features →
The health brief before class, attendance in one tap, the calendar, the hours, the playbook.
Coach features →The month's figures, VAT, the team's hours, programming, front desk, till.
Owner features →I have coached, and I have run a box. Health insurance forms on a Sunday evening, the quarterly VAT done late, the coach who is sick at 6 in the morning: I know it. No software solved that for a Belgian box. So I built the one I wish I had had.
Answers every prospect within minutes, books their trial, then follows up with members who drift away.
Every euro received gets a job: rent, wages, VAT, your own pay. You know what you can really spend.
A coach is out? One SOS, your team then your favourites are alerted, and the first to accept takes the class. Separate product, connected to WNGMN.
Instantly answers your members' practical questions, books them in or out of a class. Included in every plan.
A fixed monthly subscription based on the size of your box, with no commission on your members' money. Prices are not public yet: book a 15-minute call, Matthieu gives you the price for your box and compares it with what you pay today. Three plans: Essentiel, Box with payroll and Dimona included, and Équipe with everything. Each at €0 on your members' payments, now and later. Paid yearly: 2 months free. The first 5 boxes: yearly founder offer, 60% of the price in year one, 80% in year two. For the first 10, WNGMN moves your data over from your old software. Sign before the end of 2027 and your price stays the same for 24 months. You can leave whenever you want from the app, with all your data. 30-day trial without a bank card, nothing is charged without your consent. You only pay Mollie their per-payment fees, detailed below.
Mollie's fees, with nothing added by WNGMN. The example: a €60 monthly membership.
| Payment method | Mollie fee | On €60 |
|---|---|---|
| SEPA direct debit (monthly memberships) | €0.35 | €0.35 |
| Bancontact | €0.39 | €0.39 |
| Bank transfer | €0.25 | €0.25 |
| European Visa or Mastercard | 1.80% + €0.25 | €1.33 |
| Business card or card from outside Europe | 2.90 to 3.25% + €0.25 | €1.99 to €2.20 |
| Cash or the box's card terminal | nothing at WNGMN | €0 |
Mollie's public prices in Belgium on 27 October 2026, excluding VAT, without a Mollie subscription. These fees are paid by the box: the law forbids adding them to the price paid by a consumer for a direct debit, a transfer or a standard payment card.
No. We import your members, their plans, their attendance and their payments from your current software or an Excel file. Running direct debits are taken over without your members signing again when your current tool provides the IBAN and the mandate reference: we check that together during the call.
You pick your plan and carry on, with your members and your history. If you pick nothing, nothing is charged: your space simply stops. The trial needs no bank card.
No, the app opens from a link and goes on the home screen in one tap, on iPhone and Android. It carries your box's name.
Straight to your account, through your own Mollie account. WNGMN never touches the money: €0 on your members' payments, no commission and no margin, now and later. Only Mollie's fees apply: €0.35 per SEPA direct debit, the details are here.
For the first 10 boxes, WNGMN does it: members, plans and timetable. If your box is not up and running on day 30 through our fault, that migration is refunded.
You stop whenever you want, in the app, from My subscription: no call, no letter. The full export of your data downloads in one click, also for 30 days after stopping. Your members' SEPA mandates are on your own Mollie account: they stay yours.
If your box signs before 31 December 2027, your plan's price stays the same for 24 months: no new price list, no indexation. It is written in the terms and conditions.
Yes, each coach has their own space in the same app: their classes, attendance, the health brief, their hours, their contracts. You choose what they can do.
The member chooses what they share, with their explicit consent. Only the coaches you give the right to see the day's pain. The database is in Europe (Frankfurt). Some services, such as the AI and the app server, are provided by US companies under standard contractual clauses: details are in the privacy policy (in French).
