Stress Monitor & HRV: Stressi
Sleep & Recovery, Any Watch
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your Apple Watch already knows how stressed you are. Stressi turns HRV, sleep and heart rate into one daily Body State score, then tells you exactly what to do next.
Know how much stress your body is carrying, before it costs you the day.
Stressi is a stress monitor and HRV tracker that turns Apple Health and Apple Watch data into one clear daily score: your Body State. It reads heart rate variability, resting heart rate, sleep and activity, then explains what changed and what to do about it today.
No charts to decode. No account to create. Your readings stay on your iPhone.
WHY PEOPLE USE STRESSI
• Check your Body State before training, a hard work day or a rest day
• See whether sleep, HRV, heart rate or activity moved your score
• Get a short, specific plan instead of raw graphs
• Track stress, sleep, energy and fatigue trends in one place
• Know exactly when your health data was last synced
• Keep every reading private, on device, with no sign-up
HOW IT WORKS
Stressi compares today's signals against your own recent baseline, not a population average. Your Body State score is built from recovery, stress load, sleep quality, heart rate variability, resting heart rate and recent activity. The more consistently you wear your Apple Watch, the sharper the read becomes.
