Editor's Pick: You barely feel the ring on your hand, and it doesn't dig in when you sleep. It tracks your heart rate, temperature, and sleep in the background, so a quick glance at the app in the morning tells you how you slept. The metallic finish pairs nicely with everyday outfits without being flashy, and you don't need to take it off when washing your hands or working out.
