The R04 Smart Ring is your discreet health companion, perfect for tracking sleep and activity without the bulk of a wristband. Use it to monitor your heart rate and sleep stages throughout the night—the data syncs silently to your phone, so you wake up understanding your deep sleep patterns without any morning guesswork.
Unlike standard fitness trackers, this ring lets you control your phone's camera remotely. Set it on a table for a group photo and snap the shutter with a simple tap. It's also water-resistant to 5ATM, so you can wear it while swimming or washing hands. With multi-sport modes for running, cycling, and more, you get accurate tracking no matter how you move. The battery lasts up to 7 days, and the ring is barely noticeable on your finger.
