Klyft: AI Health & Recovery

Your body generates data 24/7. Klyft reads it all — sleep, HRV, training, nutrition — and builds one adaptive plan. Syncs with Apple Watch, WHOOP, Garmin & Oura. Try free

Klyft is the operating system for your body. Most fitness apps track one thing. Klyft connects everything — your sleep, recovery, training load, nutrition, and biometrics — into one intelligent system that adapts to your body every single day.

ONE SCORE. EVERY MORNING. Your wearable collects thousands of data points overnight. Klyft turns them into one number you can actually use: the Arc Score. Three pillars. One decision.

• Recovery — sleep quality, HRV, daily readiness
• Nutrition — calories, protein, macros, glycaemic load
• Fitness — training load, VO₂ Max, acute-to-chronic ratio

WORKOUTS THAT ADAPT TO YOUR RECOVERY Klyft doesn't hand you a static program. It reads last night's sleep, checks your recovery, and builds today's session around what your body can actually handle. Every workout adapts. Every day.

SNAP A PHOTO. NUTRITION LOGGED. Point your camera at any meal. Klyft reads the calories, protein, and macros in seconds — then folds it into your training plan. Your nutrition and your workouts finally talk to each other.

AI COACH. POWERED BY YOUR DATA.

Ask Klyft anything. "Should I train today?" "What should I eat to recover faster?" Every answer is grounded in your real biometric data — HRV, sleep, training load — not generic advice.

WORKS WITH YOUR WEARABLES

Apple Watch, Garmin, Oura, WHOOP, Fitbit, Polar, Coros, Suunto, Wahoo, Withings, and continuous glucose monitors including Dexcom and Abbott Libre. Bring the device you already own.

GROUNDED IN SCIENCE Every calculation is built from 800+ peer-reviewed studies. Your Arc Score is a formula you can audit — transparent, documented, and evolving with your body.

WHO KLYFT IS FOR

• Athletes who already wear a wearable and want their data to do more than sit on a dashboard
• High performers managing training, recovery, and nutrition across too many apps
• Anyone who checks their HRV before they check their email
