For fitness coaches and studios

Your own app for fitness coaches and studios

You have workouts that work and clients who would train with you at home too. But there are only 24 hours in a day. We build you an app under your own name where clients play a workout, pay a monthly subscription and book a session with you.

You don't need to know whether you need a website or a mobile app. Tell us what you want to offer your clients. We'll design the rest.

Sound familiar?

Clients want to train between sessions

They ask for videos. You send them over WhatsApp or Google Drive and nobody pays for them.

Your income stops when your time does

You only earn for the hours you teach. When you are ill or on holiday, the income stops.

Everything is scattered

Videos on YouTube, news on Instagram, payments in a spreadsheet, clients in a private group. Nothing lives under one roof.

Bookings through messages

You arrange sessions over Messenger and phone calls. Every no-show costs you money.

What your clients will be able to do

Train with you any time

A library of your workouts organised by goal, level and length — for example "20 minutes, beginner, back".

Pay monthly, automatically

The subscription renews on its own. No chasing payments, and an optional free trial week.

Follow a programme

A four-week programme with a new workout unlocking every day. Clients always know what to do today.

Book a session with you

One-to-one and group sessions with open spots and a reminder the day before.

See their progress

Completed workouts, streaks and notes. The kind of motivation that keeps clients with you.

Hear about what's new

A notification right on their phone: "A new 20-minute workout is up." And you can see who trains, who pays and who is drifting away.

Website or mobile app? We'll work that out

We don't expect you to answer this. After the first conversation we recommend the most sensible route based on how many clients you have, how they will train and what your budget is.

Often the starting point is a web platform that works on phones and computers and can be pinned to the home screen. Once you have more clients and want to be in the App Store and Google Play, we add a mobile app. Your content and client accounts stay the same.

We have run our own content and subscription app since 2022

Baby-Care is our own product: content from 14 specialists, a free section and full content through an in-app subscription, plus an affiliate programme with influencers. That exact model — your content, your subscribers — is the foundation of an app for coaches. We know what works and where it goes wrong.

When a ready-made tool is enough

If you are just starting out with a few dozen clients, try an off-the-shelf coaching service or a video platform first. They are quick and cheap to start with. Your own app makes sense when:

  • you want your own brand, not someone else's logo,
  • per-client fees grow faster than your revenue,
  • you need something ready-made tools can't do — for example combining videos, programmes and bookings,
  • you want your client contacts and data to belong to you.

Frequently asked questions

Do I need a lot of clients?

No. What matters more is whether your clients want to train between sessions and whether you have content they are willing to pay for. You start with a smaller version and add features as your client base grows.

Do my videos need to be professionally shot?

No. A phone, good light and clear sound are enough. Clients pay for your coaching and your programme, not for film production. We will help you structure and name the videos.

How much do Apple and Google take from subscriptions?

For subscriptions paid inside the app, the stores usually take 15% from smaller creators. When clients pay on the web, you only pay the payment provider's fee. Store rules in the EU are changing in 2026, so we work out the best route for you during the design.

Will it carry my name?

Yes. The app carries your name, logo and colours. Clients see your brand, not ours.

Can I start with videos and add bookings later?

Yes, and we often recommend it. First the part that earns money, then the part that saves you time.

How long does it take?

We work in two-week cycles and you try every finished part straight away. A simpler first version can reach people within a matter of months. You get an exact timeline together with the price after the first conversation.
