Software for fitness

Software for trainers and fitness studios so your clients see their progress and stick around.

For personal trainers and small studios there's already My Fit World, our product: routines, nutrition plans, weight and measurements, chat with the client and a schedule, all under your brand. If your gym needs something else, we'd build it to measure.

The problem

What generic software doesn't get

What it would include

What the system has to handle

01

Routines and nutrition plans

In My Fit World you create routines and nutrition plans with meals and macros, and assign them to each client.

02

Weight and measurements with charts

The client logs weigh-ins and measurements, and you both see the trend in charts.

03

Chat with the client

Messages between client and trainer inside My Fit World, without mixing work with your personal WhatsApp.

04

Session schedule

Plan sessions, reminders and notices to your clients from the same panel.

05

Under your brand

Each trainer gets a space with their subdomain and logo. Your clients log into your brand, not someone else's.

06

Mobile web, app on the way

Your clients log in from their phone's browser, with nothing to download. The iOS and Android app reaches the stores at the end of 2026.

07

Gyms, custom-built

If you run a gym with members, fees, class bookings or several rooms, we'd build it to measure, with payments through Stripe.

How we'd approach it

First we listen and give you a closed, free quote. The first version is up and running in about 3–6 weeks.

  1. 01

    Start with My Fit World

    If you're a personal trainer or run a small studio, you set up your space with your brand and invite your clients. No project needed.

  2. 02

    Bring your clients over

    Add them from the panel. If you have many in a spreadsheet, we help you import them.

  3. 03

    If you need something custom

    For a gym or a studio with specific needs, we start with one or two conversations to understand how you work. Then, a closed, free quote.

  4. 04

    First version in 3–6 weeks

    Starting with what takes most of your time: members, fees, class bookings or whatever is needed. Implementation is paid in milestones.

  5. 05

    Support and improvements

    The first year of support and improvements is included and, from the second year, a monthly fee. Anything genuinely new is quoted separately, always before we do it.

Questions

Frequently asked

Does it work for a trainer who coaches online?

Yes. With My Fit World your client logs in from their phone, sees their routine and nutrition plan, logs workouts and weigh-ins and chats with you, without you having to be there.

And for a studio or gym with several trainers?

My Fit World is designed for personal trainers and small studios. If your gym needs more (members, fees, several rooms or several centres), we'd build it to measure, with a closed, free quote before we start.

How would monthly fees be collected?

In a custom build, with Stripe connected to your account. The client subscribes, is charged every month and, if a payment fails, the system lets you know.

Who sees my clients' data?

Each client sees only what's theirs and you see your clients. Each space's data is kept separate from the rest, and communications and the database are encrypted.

Native app or web?

Today My Fit World runs in the browser, carefully built for mobile, and can be added to the home screen. The iOS and Android app reaches the stores at the end of 2026.

Does it include nutrition plans as well as routines?

Yes. In My Fit World you build nutrition plans with meals and macros, and the client sees them in the same place as their routine, without paying for a separate diet app. Its pricing doesn't depend on how many clients you have.

Shall we build it for your business?

Closed, free quote before we start. The first version running in about 3–6 weeks, with the first year of support and improvements included.
