Face scan Live

30 seconds.
30+ vitals.
Just your phone.

Hold your phone up, look at the front camera for half a minute, and Klyft hands back a full vitals panel. No cuff, no strap, no ring, no extra hardware — the only device involved is the one already in your hand.

rPPG, read off your skinRemote photoplethysmography — the camera picks up the micro colour shifts in your skin as blood moves through your face with each heartbeat, and Klyft turns that signal into vitals.
Over thirty readings per scanHeart rate, HRV (RMSSD and SDNN), respiration, blood oxygen, blood pressure, pulse-respiration quotient, stress index, SNS and PNS activity, cardiac workload, vascular capacity, haemoglobin, autonomic balance and a wellness score — a sample of the panel, not the whole list.
It lands where it countsEvery scan feeds your Arc Score and the Correlation Engine — so a camera reading sits next to your sleep, your training and your protocols, never in a silo.

Peptides & protocols Live

Every peptide,
on protocol.

Most peptide tracking is a note in your phone. Klyft turns it into a protocol you can actually run — and account for, down to the day.

Precise loggingDose, route, timing and cycle for each peptide — saved as a protocol you reuse in two taps.
Reminders & honest adherenceA nudge before each window and a streak that reflects what you actually took.
Cycles & clinician-ready historyTrack on/off phases, get told the day you taper, and export a clean PDF of everything you've run.

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.

Every input, every metricNothing sits in its own tab. What you take, how you train, how you sleep, what you eat and what the camera reads are all weighed against each other.
Effect size, window, confidenceEach relationship arrives with how big it is, the window it was observed over, and how confident Klyft is that it holds up.
Correlation, labelled as correlationWhat moves with what — not what causes what. The causal call stays with you and your clinician.
