Your wearable collects the data.
Nobody ever actually analyses it.
Upload your Whoop, Oura or Garmin export and get back a quarterly deep-analysis report written the way the longevity school actually thinks — HRV as a trend, sleep consistency before sleep scores, Zone 2 as a budget, training load as a dose.

What the report covers
HRV & recovery trend
7-day vs 28-day levels, coefficient of variation, 90-day slope, and nights below your personal baseline band — the pattern, not the daily score.Sleep architecture
Duration against the 7h30 reference, two-week sleep debt, REM and deep shares, efficiency, and onset consistency in minutes — the anchor everything else rides on.Training load
Acute:chronic ratio, monotony and strain (the Foster method), so you can see overreaching before it becomes a bad month.Zone 2 distribution
Weekly Zone 2 minutes against the 3–4 hour reference and your low/mid/high intensity split against the polarised-training benchmark.How it works
- Export your data — guides for Whoop, Oura and Garmin.
- Free readout — five headline metrics computed instantly in your browser. The file never leaves your device.
- Full report (£19) — a personal deep-analysis PDF: every number computed deterministically from your export, a "what to change next quarter" plan, delivered by email. Your file is deleted the moment the report is generated.
Privacy, structurally. No accounts. The free readout is 100% client-side. For paid reports, processing is automated end-to-end, your file is deleted after generation, and the analysis model sees only aggregate statistics — never your raw nightly data. Full policy.
Who this is for
People who read Attia, Galpin or Lyon and want their own data held to that standard: a real answer to "is my HRV actually declining?", "is my Zone 2 base big enough?", "am I accumulating sleep debt?" — with the arithmetic shown, comparators named, and no invented numbers. Every report ends with the three metrics that will tell you, one quarter later, whether the plan worked.
This is an educational analysis of your own device data — not medical advice, not a diagnosis, and no substitute for a clinician.
