Stress Monitor & HRV: Stressi

Recovery scoring that works with the watch you already own — or no watch at all. Stressi is a stress monitor and HRV tracker that turns Health Connect 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. WORKS WITH THE DEVICES YOU ALREADY HAVE Most recovery scores only work inside one brand's ecosystem. Stressi reads whatever your devices already write to Health Connect, so a Galaxy Watch, a Pixel Watch, a Garmin, a Fitbit, an Oura ring or an Amazfit all feed the same score. No extra hardware, no new subscription band. NO WATCH? YOUR CAMERA WORKS TOO No wearable, or forgot to charge it? A 30-second Camera HRV reading — fingertip over the camera and flash — feeds the same score. A wearable's continuous sensor still reads sharper, but you're never locked out. Free for everyone, no Pro required. 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 SCORED AGAINST YOUR OWN BASELINE Stressi does not compare you to a population average. It learns your personal ranges over your first couple of weeks and scores each day against them — your body, not someone else's. HONEST ABOUT THE DATA Health Connect coverage varies by watch and phone. Stressi is built for that reality: - Shows sync freshness and lets you refresh manually - Tells you when today's score is using partial data - Shows which signals are contributing today - Handles missing HRV, sleep or activity gracefully instead of pretending the score is more precise than it is 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 a wearable handy - 7-day trends and baseline-aware patterns - Guided breathing, journal, streaks and widgets 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 - Overnight breathing rate, blood oxygen, body temperature and cardio fitness (VO2 max), each compared with your own typical range. Every one is optional and works on its own. HEALTH CONNECT DATA STRESSI READS, AND WHY Stressi only reads from Health Connect. It never writes to it. Needed for the Stressi Score: - Heart rate: compares your resting and overnight heart rate with your usual level - Heart rate variability: the main signal behind the score - Sleep: duration and sleep stages show how rested you are Optional, each can be declined on its own: - Exercise: tells a hard workout apart from other strain - Respiratory rate: your overnight breathing rate, as extra recovery context - Oxygen saturation: your overnight blood oxygen, as extra recovery context - Body temperature: your overnight temperature, as extra recovery context - VO2 max: your cardio fitness sets how much a rise in heart rate should count The four overnight signals appear on the Overnight signals card. Each is compared only with your own averages. Stressi is a general wellness app for stress, sleep and recovery. ON-DEVICE BY DESIGN All processing happens on your device. No accounts, no cloud sync, no third-party tracking. Your health data stays on your phone.
