Your wearables,
finally making sense.
Sleep is the single strongest daily lever on how you age. Klyft reads every night — stages, HRV, resting heart rate, respiration — from whatever you wear, and turns it into a clear read every morning.

30+ vitals.
Just your phone.
Hold your phone up and look at the front camera for half a minute. Klyft reads the micro colour shifts in your skin as blood moves through your face — rPPG, remote photoplethysmography — and returns a full vitals panel. No cuff, no strap, no ring, no extra hardware.

more vitals in the same panel — over thirty in total, all
from one 30-second scan. What you see here is a sample, not the full list.
Wellness estimates from a camera signal, not diagnostic measurements. Klyft is a wellness tool, not a medical device, and none of this is medical advice. The panel above is an illustration, not a real reading — take anything that concerns you to your clinician.
How it works
01
Look at the front camera
Hold the phone at arm’s length, face lit evenly, and stay still for thirty seconds. Nothing to strap on, nothing to charge.
02
The camera reads the light
rPPG — remote photoplethysmography. Blood moving through your face with each heartbeat shifts the colour of your skin by a fraction the lens can still see. Klyft turns that signal into vitals.
03
It lands where it counts
Every scan feeds your Arc Score and the Correlation Engine — so a camera reading sits next to your sleep, your training and your protocols, not in a silo.
Nutrition
Food is your most
frequent input.
You eat three‑plus times a day — every one a lever on your biology. Snap the plate; Klyft fills the macros, timestamps it, and folds it into your day.

Protocols Live
Everything you take,
on protocol.
One of the pillars: what you put in your body. Peptides today — dose, timing, cycles and adherence, kept on schedule, and every dose feeds the Correlation Engine. Supplements join the same system next, so your whole stack lives in one place.
Built for how you actually run it
Precision,
not memory.
No more half-remembered doses or "did I take it this morning?" Klyft turns your protocol into something you run with intent — and can account for, down to the day.
Precise logging
Dose, route, timing and cycle for every peptide — saved as a protocol you reuse in two taps.
Reminders & honest adherence
A nudge before each window and a streak that reflects what you actually took — not what you meant to.
Cycles & clinician-ready history
Track on/off phases, get told the day you taper, and export a clean PDF of everything you've run.

Ask Klyft
A coach who knows
your whole routine.
Ask Klyft sees your protocol, your wearables, your sleep and your history. Ask it anything about your training, recovery or routine — and get an answer grounded in your own data, not the internet's.
Conversational
Talk to it.
It handles the rest.
Plan your cycle. Check your recovery. Ask why your deep sleep dropped. Klyft already has your data.
Knows your protocol
Every peptide, dose, cycle and timing — so it answers in the context of what you're actually running.
Reads your wearables
Sleep, HRV and recovery, pulled in from whatever you wear — no manual entry.
Answers, not data dumps
"Why am I tired?" gets a plain answer you can act on — not a chart to decode.
Should I cycle off BPC‑157 soon?
You're on week 4 of 6. Your plan tapers in 10 days, then a 4‑week off‑cycle. Adherence has
been 96% — a clean run. Want me to set the taper reminders?
Yes. And how's my recovery this week?
Trending up. HRV averaged 58 ms vs 52 last week, resting HR is down to 51, and sleep has held
at 7h 20m. Reminders are set for the taper.

Correlation engine Live
See what actually
moves your numbers.
Klyft weighs every input you log — peptides, training, sleep, food, face scans — against every metric it tracks, and surfaces the relationships that hold up. Each one comes with an effect size, the window it was observed over, and a confidence level.

This is correlation, labelled as correlation. The engine reports what moves with what — not what causes what. The causal call stays with you and your clinician. The panel above is an illustration, not a real reading.
Deterministic at the core
Your scores come from algorithms grounded in 800+ peer‑reviewed studies. AI handles language and vision — never the numbers.
Honest about what's live
We ship, then talk about it. Every feature on this site is in the app today — we don’t put things here before they exist.
Private by design
Encrypted in transit and at rest, and never sold. You own your health data — export or delete it whenever you choose.
A wellness tool, not medical advice
Klyft is built for healthy adults. Always consult your clinician before starting or changing any protocol.
Live longer.
Knowingly.
Download Klyft, connect the wearable you already own, and see your whole longevity picture — sleep, recovery, nutrition and the protocols you run — in one daily Arc Score.
