Oura Ring 4 Gold - Smart Ring with Sleep Tracking, Heart Rate Monitor & 8-Day Battery
Meet the Oura Ring 4—your health's new best friend. Crafted from sleek, all-titanium and smarter than ever, thanks to Smart Sensing. It's like having a mini lab on your finger, decoding over 30 biometrics to keep you in the know.
Ever wondered why you're still tired after 8 hours? The sleep tracking feature doesn't just count sheep; it dives deep into your sleep patterns to help you wake up refreshed.
Your heart's working overtime, and now you can too—with the 24/7 heart rate monitor keeping an eye on things so you don't have to.
Whether you're a marathon runner or a couch conqueror, the activity tracker has your back (and your steps, and your calories...).
Battery anxiety? Not here. With up to 8 days on a single charge, you'll forget it even needs power.
And because we know life's stressful, it throws in stress tracking and women’s health insights—because who has time to figure that out on their own?
Inside the box: The Oura Ring 4 (obviously), a charger, USB cable, some light reading (information booklet), and a quick start guide for those who don't like to wait.
Heads up: Don't skip the sizing kit. Unless you're into wearing a ring that's either a tourniquet or a hula hoop.
