Camera coach, plate scan, smartwatch sync, a program that adapts to your real progress. Open a feature to see how it works.
Two things make a program fail: executing badly, and eating by guesswork. KLYN handles both for you — all that's left is showing up.

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.

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

Training, nutrition and coaching in the same program. Nothing to build, nothing to look for: you open it, you follow it.

A single session with a personal coach costs more than a whole month of KLYN.
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.
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.
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.
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.
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.
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.
