## What is Klyft?

Klyft is the operating system for your body.

Most apps track one thing. Klyft connects everything — sleep, recovery, training, nutrition, your labs, even your face — 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 impact
Fitness — training load, intensity, acute-to-chronic ratio

And it's honest: if one pillar collapses, your score is capped. You can't mask a bad night of sleep with a great workout.

KNOW YOUR BIOLOGICAL AGE
Your birth certificate holds one number. Your biology holds another. Klyft fuses your blood markers, wearable data, and fitness signals into your Biological Age, with a likely range, a confidence level, and your pace of aging as it emerges. Train it down. Watch it change.

SCAN YOUR FACE. SEE YOUR VITALS.
Thirty seconds of front camera. Heart rate, HRV, breathing rate, a blood-pressure estimate, and your cardiovascular age — no wearable required. Camera-based wellness.

YOUR LAB REPORTS, DECODED
Photograph any lab report, upload a PDF, or type values in. Klyft extracts your biomarkers — 63 markers across 10 panels — shows where each value sits against its reference range, and tracks how every marker moves across reports. Blood tests stop being paperwork. They become part of the picture.

WORKOUTS THAT ADAPT TO YOUR RECOVERY
Klyft reads last night's sleep, checks your recovery, and builds today's session around what your body can handle — then debriefs you with pace, heart-rate, and effort analysis for runs, rides, swims, and strength. On Garmin? Send the workout straight to your watch.

SNAP A PHOTO. NUTRITION LOGGED.
Point your camera at any meal — or a barcode, or a menu, or just describe it. Klyft reads calories, protein, macros, fiber, and glycaemic impact, ingredient by ingredient, and folds it into your plan.

IN SYNC WITH YOUR RHYTHMS
Track your cycle: period calendar, phase projections, daily logs, monthly check-ins. And your body clock: Klyft maps your chronotype, times your meals, sleep, and focus around it, and builds jet-lag plans when you travel.

AI COACH. POWERED BY YOUR DATA.
Ask Klyft anything — type it, say it, or point the camera at it. "Should I train today?" "Why is my HRV down?" Answers grounded in your data, not generic advice.

AT A GLANCE
Home-screen widgets put your Arc Score, Biological Age, and sleep stages one glance away. Morning Brief walks you into each day. Streaks keep you consistent.

WORKS WITH YOUR WEARABLES
Apple Watch, Garmin, Oura, Fitbit, Polar, Withings, Strava, Google Fit, and Samsung Health. Bring the device you already own.

TRANSPARENT BY DESIGN
No black boxes. Klyft's scoring is deterministic and documented — anchored to peer-reviewed models, showing its confidence instead of hiding it. When Klyft isn't sure, it says so.

WHO KLYFT IS FOR
Longevity-minded people who want to know their Biological Age — and lower it
Health optimizers tracking sleep, nutrition, labs, and recovery across too many apps
Wearable owners who want their data to do more than sit on a dashboard
Anyone who checks their HRV before they check their email
