Nervio Recovery Signals
Health & Fitness
Free · In‑App Purchases
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
One-time purchase. No subscription, ever.
• Home Screen Widgets — live recovery and stress on your Home Screen and Lock Screen
• Live Activity — your recovery ring in Dynamic Island and on the Lock Screen all day
• All future Pro features included at no extra cost
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.
REQUIREMENTS
iPhone with Apple Health data (7+ days recommended to establish a baseline)
iOS 17 or later
Apple Watch optional but recommended for HRV data
