    The right move, the right plate.
    Every day, without thinking about it.

    Two things make a program fail: executing badly, and eating by guesswork. KLYN handles both for you — all that's left is showing up.

    Every session counts, because it's done right.

    You press a button and the session runs on its own. The coach announces the exercise, the video shows you the move, and your camera counts the reps, correcting you out loud if your position slips.

    • 80 exercises filmed and explained, angle by angle
    • Sets and rest times chained automatically
    • Reps counted by the Camera Coach — nothing is filmed or sent
    • From 4 to 6 sessions per week depending on the program

    You eat normally. The app does the math.

    Three meals a day designed for your goal, with calories and macros shown. And when you eat something else, one photo is enough: the dish is recognized, the portion estimated, the day updated.

    • 84 meals per program: breakfast, lunch, dinner

    The founder of KLYN

    I lost 18 kilos.
    Then I turned it into an app.

    Six chapters, and what each one became in the app.

    1. 01

      I tried everything. Failed everything.

      Diets, gym memberships, downloaded programs: fifteen days, never more. Every time the same conclusion — I don't have enough willpower. That was wrong. I simply had no method.

    2. 02

      The real culprit is the plan.

      A rigid program doesn't care about your level, your schedule or what you actually eat. So the first missed session becomes a failing, the failing becomes guilt, and the guilt makes you drop everything. It's not up to you to adapt to the program. It's the other way around.

    3. 03

      Four weeks. Zero equipment.

      I started over from scratch: no gym, no equipment, two square meters of floor and three guided sessions a week. Every movement explained, every week a notch above the last, nothing left to chance. For the first time in my life, I stuck with it.

    4. 04

      The turning point wasn't in the gym.

      It was on my plate. Stopping the guesswork, knowing exactly what to eat, checking every meal. That's when the kilos started coming off — four to five the first month, without ever depriving myself once.

    5. 05

      Three months. Eighteen kilos.

      No extreme diet, no gym every day, no life put on hold. A structured, progressive method that holds up in a real life — with work on the mind as serious as the work on the body. GALA wrote an article about it.

      What I would have wanted.

      I put this entire method into an app, so it would work for someone other than me too. Five coaches, six programs, nutrition, the mind. Everything that took me years to understand, you get on the first day of your trial.

    What you're telling yourself right now

    The real questions,
    the real answers.

    01I've already tried ten times. Why would it work this time?

    Because the other nine times, you followed a plan written for someone else. Here the program locks onto your real level and readjusts when you skip a session — instead of leaving you a week behind and ready to give up.

    02I don't have the time.

    Sessions run 20 to 40 minutes, 3 to 6 times a week depending on the program, and you choose the days. No commute, no locker room, no slot to book: you set your phone down and you start.

    03I'm a complete beginner.

    Two of the six programs are built to start from zero. Every movement is filmed and explained before it's asked of you, the intensity starts from your level, and the Camera Coach corrects you out loud if your position slips.

    04I have neither a gym nor equipment.

    Two complete programs are done with bodyweight only, in two square meters. The others call for dumbbells or a gym — it's stated clearly before you choose.

    05And nutrition, do I have to weigh everything?

    No. You get three meals a day already calculated for your goal. And when you eat something else, one photo is enough: the dish is recognized, the portion estimated, the day updated.

    06And what if I don't like it?

    You have three days to try everything without paying. If you cancel before the end, you're never charged. No commitment, no minimum term, cancellation in two clicks from your account.

    07Does it work on a computer?

    Yes. The app is on the App Store, on Google Play and directly in your browser at klyn-app.org — same account, same progress, you move from one to the other without losing a thing.
