The IP68 waterproof rating means you can swim, shower, or sweat without worry. With multi-sport mode, the ring automatically recognizes walks, runs, and cycling. The gentle vibration alerts you to call, text, or goal notifications. Use the free app to see detailed sleep stages, heart rate trends, and step counts.
