About Stress Monitor & HRV: Stressi
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 data into one clear daily score: your Stressi Score. 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 Stressi Score 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 APPLE WATCH GIVES THE SHARPEST READ Wear your Apple Watch and Stressi builds your score from continuous HRV, resting heart rate, sleep and activity data — the fullest picture of how your body is recovering. NO WATCH? YOUR CAMERA WORKS TOO Don't have an Apple Watch, or left it charging? Take a 30-second Camera HRV reading instead: hold your fingertip over the rear camera and flash, and Stressi reads your pulse directly. It's a real HRV reading and feeds the same Stressi Score — a wearable's continuous sensor is still sharper, but you're never locked out. Free for everyone, no Pro required. HOW IT WORKS Stressi compares today's signals against your own recent baseline, not a population average. Your Stressi Score is built from recovery, stress load, sleep quality, heart rate variability, resting heart rate and recent activity. WHAT'S INCLUDED • Daily Stressi Score • Why-it-changed explanations for every move • Today Plan with simple next steps • HRV, sleep, heart rate, activity and energy signals • Camera HRV check when you don't have your watch • 7-day trends and baseline-aware patterns • Manual refresh and data freshness indicators STRESSI PRO • 30, 90 and 365-day Stressi Score trends • Deeper patterns, triggers and signal breakdowns • Recovery forecasts and premium daily plans • Guided programmes, reports, exports and journal correlations • Guided breathing and advanced widgets PRIVACY FIRST Your health data stays on your device. No accounts, no cloud sync, no third-party tracking. Stressi is built for people who want a real physiological read without handing over their health history. SUPPORTED LANGUAGES English, Spanish, German, French, Italian, Portuguese, Japanese, Korean, Chinese See your stress, understand what changed, and recover with a plan.
