About InWave: Stress & HRV
A little more understanding. A little more room to breathe.
InWave helps you explore your body's stress and recovery signals with Apple Watch, so you can find a rhythm that feels right for you.
UNDERSTAND YOUR DAY
• See your latest HRV-based stress estimate and daily overview.
• Explore patterns in stress, resting heart rate, sleep and activity.
• Glance at your latest state with Apple Watch complications.
MAKE TIME FOR YOURSELF
Try guided breathing, mindfulness and body relaxation exercises. Choose a short pause or a longer practice, and build a routine at your own pace.
MAKE IT YOURS
Set goals for sleep, steps, water and mindfulness. Choose or create themes that give your wrist a personal touch.
INWAVE PRO
Basic stress views are free. Pro unlocks detailed history, longer-term trends, more themes and additional relaxation content. Choose a monthly or annual subscription, or a one-time Lifetime purchase. Available features depend on your plan.
HRV insights require a compatible Apple Watch and permission to read Apple Health data. Readings and update frequency depend on the data your devices record and your settings; monitoring is not continuous.
Payment is charged to your Apple Account when you confirm a purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel subscriptions in your App Store account settings. Any trial or offer eligibility and the price are shown before purchase.
InWave is for general wellness and information. It does not provide medical diagnoses or treatment, and cannot replace advice from a qualified health professional.
