NoStress: HRV Stress Tracker

See stress building up before you feel it. NoStress turns the heart rate variability (HRV) your wearable already records in Apple Health or Google Health into one simple stress level, next to resting heart rate, sleep and blood oxygen. Glance at your stress on the Apple Watch face, check the daily overview on iPhone, and follow weekly and monthly trends. Wear a Fitbit as well? Its steps, heart rate and sleep merge through Google Health sync without double-counting. Works with any device: Apple Watch, Fitbit, or anything else that writes to Apple Health or Google Health, such as Oura, Whoop, Garmin or Withings. NoStress reads HRV, heart rate, resting heart rate, sleep and blood oxygen from there. Monitor your stress levels through heart rate variability (HRV) data from your Apple Watch, Fitbit or any device that syncs to Apple Health. Simple, clean interface for understanding your body's signals.
