How we measure
activity
Heart rate shows how hard your body is working. Because health benefits depend on intensity, it’s a reliable way to measure activity. We use heart-rate data to capture your activity as it happens from your wearable or let you log activities manually.
Works with your watch
Mia connects with most popular heart-rate watches, including Garmin, Polar, Fitbit, and Apple Watch. Activity syncs automatically in the background.
