Stay in tune with your body all day with advanced wellness tracking that includes a cEDA sensor to detect signs of stress, sending real-time notifications so you can respond with calming activities like guided breathing sessions right from your wrist. Track your sleep automatically, including time spent in light, deep, and REM stages, and monitor your resting heart rate—an essential indicator of heart health. For those tracking menstrual health, easily log periods, symptoms, and ovulation estimates to better understand your cycle. With built-in GPS, you can leave your phone behind and still track pace and distance during your favorite workouts, from running and biking to yoga and strength training. Plus, it’s water-resistant up to 50 meters, making it perfect for the pool, shower, and beyond.
