Observa: HRV & Recovery Score
by Antti Aittamaa
Description
Understand what your body is actually telling you. Observa turns Apple Health data into a daily recovery story — with the deeper analytics free for 7 days and the core insights free forever. Local-only. No cloud. No extra wearable.
RECOVERY & READINESS
A daily readiness score built from HRV, resting heart rate, sleep quality, and training load. See exactly which signals are pulling your score up or down, and how today compares to your personal baseline — not a population average.
SLEEP, MEASURED LIKE A SPORTS SCIENTIST WOULD
Sleep score, REM and deep sleep stages, efficiency, sleep debt, consistency, and timing. Observa scores not just hours, but quality, restoration, and how your sleep is trending across weeks.
HRV, STRESS & HEART SIGNALS
Physiological stress scoring from HRV, resting HR, sleep fragmentation, and training load. Advanced HRV metrics including RMSSD, pNN50, and autonomic balance. ECG-based insights and atrial fibrillation (AFib) burden tracking when your Apple Watch detects them. Useful for anyone tracking POTS, Long COVID, dysautonomia, or simply paying attention to their autonomic nervous system.
CYCLE-AWARE BASELINES
For people with a menstrual cycle: Observa adjusts your baselines and readiness score across the follicular, ovulation, and luteal phases. Your HRV and resting heart rate naturally shift with your cycle, and a single fixed baseline lies about both.
YOUR PATTERNS
This is where Observa is different. The correlation engine analyzes weeks of your data to find real associations: how your exercise affects sleep quality, how alcohol changes recovery the next day, how stress shows up in HRV before you feel it. The patterns that actually move your needle — surfaced, not buried.
WIDGETS & DAILY COACHING
Recovery score, sleep breakdown, heart signals, weekly stress, daily guidance — all on your Home Screen. A short, calm coaching note each morning explaining what your body is asking for today, in plain language. Updated after every sync.
BUILT FOR PRIVACY
No account. No sign-up. No cloud sync. No ads. No analytics. No "free with your data" trade. Your health data never leaves your device. Period.
WORKS WITH WHAT YOU HAVE
iPhone and Apple Watch. That's all you need. Observa reads from Apple Health — the data your watch already collects.
FREE & PREMIUM
Observa is free to explore. The full readiness score, 30/90/180-day trends, the correlation engine, advanced HRV metrics, cycle-aware baselines, AFib burden, and the full widget set are available with a 7-day Premium trial. Cancel anytime in Settings. No hidden fees, no dark patterns.
