KLYN - 28-Day Fitness Coach

Your camera counts your reps. Your plate is scanned from a photo. Your watch fine-tunes your calories. Training, nutrition and mindset in one app.

KLYN is the fitness coach you always wanted — without the price of personal coaching. Training, nutrition, mindset: it's all in here, and it all adapts to you.

6 PROGRAMS, ONE FOR EVERY GOAL • Shape Bodyweight — fat loss, zero equipment, to start or start again • Shape Equipment — toning with dumbbells, at home or at the gym • Build Start — beginner muscle gain, the solid basics of strength training • Build Strong — advanced muscle gain, hypertrophy and strength • Military — intense conditioning, military-style calisthenics • KLYN Mind — meditation, breathing, mental recovery Every program is structured into weeks and days, with real progression — not a random list of exercises.

CAMERA COACH — YOUR SESSION, GUIDED, HANDS FREE One button starts the whole session. The coach calls out each exercise, your camera counts your reps and your rest time, corrects your position out loud when it's wrong, and chains the sets and rest periods to the end. 100% on your phone: nothing is filmed or sent anywhere.

SESSIONS THAT ADAPT TO YOU • Adaptive program — KLYN adjusts reps, sets and intensity based on how you felt after each session • Freestyle session — not in the mood for today's program? Generate a custom session based on your location, your equipment, your intensity and the area you want to work

NUTRITION THAT THINKS FOR YOU • Full 28-day plan, 3 meals a day, with every training program • Photo scan: take a picture of your plate, the AI recognizes the dish and calculates the macros • "What's in your fridge?": tick what you have, KLYN suggests a meal that fits your goal • Allergen and diet alerts: whatever you declared is checked at every meal

CONNECT YOUR WATCH, YOUR NUTRITION SHARPENS ITSELF Apple Watch or any watch linked to Apple Health: after a few days, your calorie target moves from the quiz to your real measured expenditure (steps, active calories, sleep, resting heart rate). The AI Coach takes it into account too. Optional, never required.

ON YOUR HOME SCREEN AND LOCK SCREEN iOS widget: progress ring, sessions done and remaining, next session, steps, calories, weight. And during training, your session shows live on the lock screen and in the Dynamic Island.

YOUR PERSONAL COACH + AI COACH Maya, Atlas, Onyx, Lena, Kaia — each program has its own dedicated coach, with daily messages and detailed exercises. And an AI Coach answers your questions about training, nutrition or your progress, any time.

PROGRESS THAT KEEPS YOU COMING BACK • XP and levels, from Recruit to the top • Streak, milestones (day 7, day 14, program completed), a summary every Sunday • A reminder if you haven't trained in 24h • Refer a friend: +30 days of access for both of you
