Nervio Recovery Signals

Nervio turns your Apple Health data into a clear, daily recovery signal. No subscription. No extra hardware. Just the answer to one question: is your body ready today?

YOUR DAILY RECOVERY SIGNAL

Nervio reads heart rate variability, resting heart rate, sleep, and steps from Apple Health. It builds a personal baseline from your recent history, then scores each day from 0 to 100 — a signal calibrated to you, not a generic average.

• Recovery Score: 0–100, color-coded so a glance tells you everything • Stress Score: physiological stress estimated from HRV patterns • Trend Charts: see how your recovery shifts week over week • Daily Summary: a one-line read on what your metrics are saying today

APPLE WATCH

Recovery and stress scores sync to your wrist automatically. Nervio's Apple Watch app shows your ring and score at a glance, with complication support for every watch face.

NERVIO PRO

PRIVACY BY DESIGN

All processing happens on your device. Nervio never uploads your health data, requires no account, and has no cloud sync. Your data stays yours.
