Run your protocol right.
Klyft gives you the precision longevity demands today — peptides, recovery and a daily readiness score — on a foundation built to grow into the full picture.
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.
Your wearables,
finally clear.
Connect any major wearable. Klyft reads every night — sleep stages, HRV, resting heart rate and respiration — and turns it into one clean read every morning.
A coach who knows
your whole routine.
Ask Klyft sees your protocol, your wearables and your history. Ask anything about your training, recovery or routine — and get an answer grounded in your own data.
Snap the plate.
Klyft does the math.
Photograph any meal. Klyft recognises what's on the plate, fills in the macros and timestamps it — no barcodes, no databases, no decimal points.
Your day,
in one number.
The Arc Score is a single 0–100 readiness number, computed by deterministic algorithms grounded in 800+ peer-reviewed studies — never guessed by a language model.
The rest of the picture.
Peptides are the live foundation. Next, Klyft connects your protocol to the rest of your biology — so you'll see not just what you took, but what it actually changed.
Bloodwork, decoded
Upload any lab panel — Klyft reads 50+ biomarkers and maps them to longevity-optimal ranges.
In developmentSupplement stack
Track supplements right alongside your peptides — one stack, never doubled up or forgotten.
In developmentBiological age
Turn your biomarkers and vitals into one number — how fast you're aging — and watch it bend.
In developmentCausal engine
Isolates what actually moves each metric — by how much, and how sure we are.
