InWave: Stress Monitor
HRV & Habits for Apple Watch
Free · In-App Purchases
See the stress signals your Apple Watch picks up. InWave brings HRV, heart rate, and real-time stress into a clear daily view, so you know when to rest and recharge.
InWave helps you understand stress and recovery with your Apple Watch. It brings heart rate variability (HRV), resting heart rate, and other Apple Health information together in a clear picture of your day. No alarm bells, just helpful context for knowing when to keep going and when to recharge.
WHY HRV?
The small changes in time between heartbeats can offer clues about how your body responds to daily demands. InWave compares your readings with your own history and presents them as four easy-to-read stress states: Great, Normal, Elevated, and Overloaded.
