ULTRAHUMAN Ring Air Smart Ring Rose Gold Size 7 - Sleep & Fitness Tracker with Heart Rate, HRV, Skin Temperature, 6-Day Battery, 10 ATM Water Resistance

The ULTRAHUMAN Ring Air stands out by packing lab-grade health tracking into an ultra-light titanium ring that you can wear 24/7 without a screen or constant charging. Unlike bulky wristbands, it focuses on recovery, sleep quality, and circadian rhythm insights, giving you a clear picture of how your body responds to daily stress and training.

Highlights

• Aerospace-grade titanium outer shell with hypoallergenic resin inner for all-day comfort
• Tracks heart rate, HRV, skin temperature, movement, and calories burned
• Up to 6 days of battery life with a 2-hour charge via included charging cradle
• 10 ATM water resistance – safe for swimming and showering
• No screen, no vibrations – just subtle, continuous data collection

In daily use

Slip the ring on and forget it. The Ultrahuman app translates raw sensor data into three simple indices: Movement, Sleep, and Recovery. It learns your personal baseline and nudges you when you're overreaching or under-recovering. Because there's no display, you avoid notification overload and check insights on your phone when it suits you.
