Ultrahuman Ring Air smart ring raw titanium maat 14 - fitness- en slaaptracker

The Ultrahuman Ring Air stands apart from wrist-worn trackers by packing clinical-grade sensors into a slim titanium band that weighs less than a standard wedding ring. This Raw Titanium, size 14 model is built for continuous health monitoring without a screen, notifications, or charging anxiety—just passive, always-on data collection.

Highlights

• Fighter-jet grade titanium outer shell with medical-grade epoxy resin inner lining
• PPG heart rate sensor, skin temperature sensor, and 6-axis motion sensor
• Up to 6 days of battery life with a 45–60 minute charge time
• 10 ATM water resistance—safe for swimming and showering
• Compatible with iOS 15+ and Android 8+ via Bluetooth Low Energy 5.0

In daily use

The ring tracks heart rate, HRV, sleep stages, skin temperature trends, activity, and recovery. On-device storage holds up to 7 days of data, and the included charging cradle refills the battery in under an hour. With a width of 2.8 mm and thickness of 2.45 mm, it disappears on your finger while you go about your day.
