Premium health intelligence
Know your body
like never before.
All the recovery, HRV, sleep-debt and correlation analytics you’d get from a WHOOP or Oura subscription — built from the Apple Health data you already have. No wearable to buy. Real science, scoped entirely to you.
- Your data stays yours
- No wearable required
- Built on real science
Everything your body is telling you
One dashboard. Every signal, beautifully read.
Recovery branch dominant — your body is in repair mode.
Your body reads 5 years younger than your calendar age.
What it measures
Five lenses on one body. All from data you already have.
Recovery
A recovery score you can actually trust
Every morning, Healthi blends HRV, resting heart rate, respiratory rate, sleep and skin temperature into one readiness score — with the exact contributor breakdown, and an Oura-style cap so one bad signal never inflates a green day.
Heart
HRV status, the way the pros read it
lnRMSSD status bands, resting-HR and respiratory deviation, autonomic balance, and a Poincaré scatter that shows your beat-to-beat variability the way a cardiologist would — all tracked against your own rolling baseline.
Sleep
Sleep architecture, not just hours
Deep, REM and core stages, a full hypnogram, efficiency, and a running sleep-debt balance against your personal need. See the nights that cost you — and the ones that paid you back.
Mind
The correlations no single app shows you
A statistical engine (Pearson with permutation testing and false-discovery correction) surfaces the relationships that are real — like how last night’s HRV moves your recovery — and hides the noise that isn’t.

What is Healthi?
Healthi is a premium health-intelligence dashboard that turns your Apple Health data into recovery, HRV status, sleep debt, and personalized statistical correlations — the kind of analytics you normally only get from a WHOOP or Oura subscription, without needing their hardware.
Do I need a wearable like WHOOP or Oura?
No. Healthi reads the data your iPhone and any connected devices already write to Apple Health. If you do have an Apple Watch, Oura, or WHOOP syncing into Apple Health, Healthi uses that richer data automatically.
How is the recovery score calculated?
Healthi blends heart-rate variability (HRV), resting heart rate, respiratory rate, sleep quality, and skin temperature, each scored against your own rolling baseline. A single severely out-of-range signal caps the overall score, so one bad night cannot produce a falsely green day.
What makes the correlations trustworthy?
Healthi computes Pearson correlations between your metrics, then runs a permutation test (hundreds of shuffles) and applies Benjamini-Hochberg false-discovery-rate correction. Only relationships that survive that statistical scrutiny are shown, so you see real patterns rather than coincidence.
Is my health data private?
Yes. Your data is scoped entirely to your account — every record is tenant-isolated, and one user can never see another user’s data. Healthi never sells health data.
How much does Healthi cost?
You can start free at dash.healthi.live. Create an account, connect your Apple Health export, and your dashboard populates automatically.
Your data is already there.
