Software for fitness

Software for trainers and fitness studios where your clients see progress and you get paid on time.

An operating system for coaches and studios: routines, nutrition plans, measurements, progress photos, chat with the client and recurring billing. Designed so the client doesn't drop off after the third month.

SCROLL

The problem

What generic software doesn't get

01
Adherence
A significant share of a coach's clients drop off in the first months. The real cause isn't the plan; it's that they lose contact and stop seeing progress. A spreadsheet + WhatsApp doesn't fix that.
02
Recurring billing
Charging dozens of clients manually each month is half a day's work. And there are always a few who don't pay on time and no one knows who until it shows in revenue.
03
Measurements and photos
Without proper photo and measurement history (weight, waist, body fat) that's comparable, the client doesn't see progress even when they have it. And if they leave, you lose the data.
04
Routines and nutrition
Building a custom routine in a spreadsheet, sending it as PDF and waiting for feedback doesn't scale beyond 10 clients. You need reusable templates and a place where the client sees them.

What's included

The complete operational system

Routine and nutrition templates

Build a routine once; assign and customise it in 30 seconds for each client. Same with nutrition plans.

Measurements and visual comparison

Weight, perimeters, body fat, sleep. Trend charts. Side-by-side comparison of progress photos by month.

Chat with the client

Built-in messaging client–coach. Voice notes, photos, videos. Without going through WhatsApp and mixing personal life with work.

Recurring billing

Integrated payment gateway. Monthly subscriptions or by bond. Automatic retries, failed-payment notices, soft dunning.

Client onboarding

Initial questionnaire, goals, baseline photos and signed data consent. All saved in their file.

Mobile app or web for the client

The client logs in from mobile, sees today's routine, ticks sets, uploads photos and chats with the coach. All in one place.

Multi-coach or studio

Several trainers sharing the same system, with their own clients and the studio's commission rules.

How we build it

From audit to full operation. You use the system from day one.

01
Discovery with the coach
One week looking at how you work today, how many clients you have and what eats your time. We come out with a realistic 3-month scope.
02
Functional MVP in 3–4 weeks
Templates, client file, measurements, photos and billing. You use it with real clients from week 4.
03
Client migration
We import clients and data from the previous spreadsheet/Notion/tool. Zero loss of historical progress.
04
Full operation
Chat, mobile app, recurring billing, challenges, adherence metrics. Everything you need to retain.
05
Growth
When you grow into a studio or several coaches, the system scales without re-licensing. Flat maintenance.

Questions

Frequently asked

Does it work for a coach who works online?

Yes, it's largely designed for that. The client accesses from mobile, follows the routine, uploads photos and talks with you without you needing to be on site.

And for a physical studio with several coaches?

Also. Multi-coach mode, assigned clients, commissions, in-person session agenda and centralised billing.

How do we collect monthly fees?

Stripe is integrated as the payment gateway with your account. The client signs a subscription and gets billed monthly. If a payment fails, the system retries, notifies and blocks access if needed.

Are progress photos private?

Yes. Each photo is linked to the client and only accessible by them and their coach. Can be deleted on request. Images are stored in private EU storage.

Native app or web?

Mobile-optimised web by default, working perfectly on iOS and Android as an installable PWA. If you need a native app with strong push notifications, we add it.

Shall we build it for your business?

MVP in production in 3–6 weeks. Closed budget before we start. Code and data are yours.
