InWave is your calm, science-based stress companion for Apple Watch. It reads the signals your body is already sending—Heart Rate Variability (HRV) and resting heart rate—and turns them into a clear daily picture of your stress and recovery. No noise, no alarm bells. Just a gentle, honest read on how you're really doing. WHY HRV? The tiny variations between your heartbeats reveal how your nervous system is coping. When HRV drops or your resting heart rate climbs above your usual range, your body is under strain. InWave watches these signals around the clock from your Apple Watch and translates them into four easy states—Great, Normal, Elevated, and Overloaded—so you always know where you stand.
