Ultrahuman RA-RT-Size14-US Raw Titanium, Size 8 Smart Ring Health Tracker
Available Options
For the active individual seeking deeper health insights beyond steps and calories, the Ultrahuman Ring AIR offers a discreet way to monitor your body's signals throughout the day. Imagine checking your stress rhythm score after a hectic meeting to decide if you need a walk or a break, rather than guessing how you feel.
This smart ring tracks sleep stages, heart rate variability, and women's health metrics like ovulation with biomarker precision, all without a subscription. The titanium build feels barely there during workouts or sleep, and the included sizing kit ensures a snug fit to avoid inaccurate readings. You get actionable nudges—like when to limit caffeine for better sleep—based on your personal data, helping you make small, informed changes for long-term wellness.
