Diaboliq

From fitness enthusiastsfor fitness enthusiasts.

We know the value of a good plan, the motivation after a great workout and the challenge of sticking with it for months. That is why we are building the coach we never found ourselves.

Vision

Everyone who trains deserves a coach.

For a long time, a professional plan was something for the few: athletes with a coach, people with plenty of time and money. We want to make sound, personal training accessible to everyone, beginners and pros alike, and help you understand your progress. And we want to show how a company works that combines experience, human responsibility and extensive automation.

Mission

A coach in the app that understands your goal and builds you a plan that fits you.

It asks about your goal, your experience, your time and your equipment: the everyday life your training has to fit into. It plans only with exercises from our catalogue, and every plan goes through a fixed safety check without AI before it reaches you. That gives your passion for training a clear direction.

Our story

  1. 10.71s

    The track

    It starts with a sprinter: 100 metres in 10.71 seconds, as a junior. Our founder comes from athletics.

  2. Badges

    The military

    Then came the military, and with it a soft spot for badges: you only wear one once you have earned it. That is exactly how we do it in the app.

  3. Strength

    The gym

    After that: strength training, muscle building and the search for an app good enough for a pro. He never found one.

  4. 5 years

    The idea

    For more than five years he has carried the idea with him and kept refining it: a coach for everyone, one that makes starting easy for beginners and pushes pros.

  5. 2026

    Built with Claude

    Then the building begins, with Claude by Anthropic: more than five years of ideas become a few weeks of building.

    • August the first line of code, and with it the safety check for every plan
    • September the catalogue, the app with the coach, your Glut and Ember
    • October challenges, check-in at partner gyms and the shop

  6. Today

    An AI company

    Code, checks and decision papers are created with AI. People review them, set priorities and decide.

Sticking with it is the hardest part.

A good plan is only the beginning. That is why Diaboliq has a game built in where only real training counts: it rewards consistency, not screen time.

  1. Funke

    from 1 workout

  2. Glut

    from 10 workouts

  3. Flamme

    from 50 workouts

  4. Feuer

    from 100 workouts

  5. Inferno

    from 250 workouts

Your Glut
Every workout makes it grow, through five stages from Funke to Inferno and in your colour. It never goes out.
Ember
One for every training day up to your weekly goal, two more for a full week, plus check-ins and challenges. You redeem them in the shop in the app.
Challenges
One for your stage every two weeks, a special with medals every four weeks, one just for you every month, plus bingo, colour battle and seasons. With friends, you create your own.
Badges
Earned, never bought: your badge shows your stage and your workouts, and in the seasons you win bronze, silver or gold.
Records
A new personal best sparks right in the set, and after training you see at a glance what you achieved.
Rankings
Only if you want: they stay off until you switch them on, and show only your nickname in a small group.

What we believe in

We develop Diaboliq as people who love to train, for the joy of getting stronger. That is why what counts for us is what works in everyday training.

Honesty counts.
Your Glut only grows with real training: at least one set, ten minutes, once a day.
Safety before speed.
Every plan from the coach goes through the same fixed check, with rules instead of AI. Whatever fails it never reaches you.
Recovery is part of it.
Every eight weeks you can take a week off without breaking your streak. And your Glut never goes out.
Straight talk, no promises.
We don’t promise you kilos lost in weeks. We give you a plan; the training is up to you.
You shape your training.
Swapping exercises, adding them or building a plan yourself is always possible. We are responsible for the app; you decide what you train.
Care with your data.
We only store health information with your consent, and you can delete your account right in the app.

Diaboliq grows from the same attitude that drives us in training: work attentively, learn from experience, get better step by step.

An AI company from day one

Without Claude by Anthropic, Diaboliq would not exist. Claude did not just design and program: it helped build the whole company.

We use AI where it makes knowledge accessible, simplifies processes and prepares decisions. That frees up room for what needs our attention: the quality of the app, your needs and the further development of Diaboliq.

What Claude has done for us:

  • designed and built the app, the website and the admin tools
  • built the safety check every plan has to pass
  • checked the catalogue exercise by exercise
  • translated the app and the website into English, French and Spanish
  • prepared the basis for the decisions on founding the company
  • set up the merch logistics, from production to returns
  • drafted the privacy and legal texts that our lawyer reviews
  • checked every change before it goes live

People make the decisions: the idea, the brand and every decision come from us. And the coach in the app is Claude too.

Hundreds of hours of work have gone into the catalogue: 3,491 exercises, each with muscle groups, equipment, contraindications and alternatives. It is the basis of every plan: which exercises suit your goal, what works with your equipment and which exercise can replace another.

From fitness enthusiasts for fitness enthusiasts: that is where Diaboliq comes from, and our yardstick for everything still to come.
