Simple Stress Watch shows your heart rate variability as a one-glance recovery meter on Apple Watch faces. It reads HRV from Apple Health, compares it to your personal rolling baseline, and renders a single number with a colored recovery zone: green above baseline, white around it, yellow below, red well below. Complications support every accessory family so you can put the meter on any watch face. On iPhone, a Lock Screen widget shows the same reading and meter at a glance, and you can view today’s HRV readings in the app or on your Home Screen with a chart widget. It’s designed to be extremely simple and minimal. Your data stays on your device: no accounts, no uploads, no analytics. Simple Stress Watch is a general wellness app and not a medical device. It does not diagnose, treat, cure, or prevent any condition. For medical concerns, please consult a healthcare professional.
