Track Everything. Wear Nothing But a Ring.
The Ultrahuman Ring AIR in Raw Titanium is a next-generation smart ring that delivers smartwatch-level health data in an ultra-lightweight, screenless design. At just 2.4–3.6g, it’s one of the lightest wearables on the market — you’ll forget you’re wearing it.
Why the Finger Beats the Wrist
Finger-based biomarker tracking is more accurate than wrist-based monitors due to higher blood flow and arteriole density, giving you cleaner, more reliable data around the clock.
Built Tough, Worn Comfortably
The outer shell is aerospace-grade titanium reinforced with a tungsten carbide coating for scratch and wear resistance. The inner surface features a medical-grade, hypoallergenic epoxy resin lining — smooth, seamless, and safe for all-day wear. Water resistant to 100m/10ATM, so it goes where you go.
