## Long description

The Ultrahuman Ring AIR is a compact smart ring for men and women that continuously monitors sleep, recovery and daily activity. With a slim silver finish and a low-profile 2.8 mm thickness, the ring is designed for all-day and night wear. It connects via Bluetooth to compatible Android (8+) and iOS (15+) devices and includes a USB-C to USB-C charging cable. The ring uses a 24 mAh LiPo battery that supports up to 6 days of typical use.
Advantages
The ring provides fingertip biomarker measurements for higher accuracy compared with many wrist-worn trackers, improving the precision of heart rate, heart rate variability (HRV) and skin temperature readings. At about 2.4 grams and with a hypoallergenic inner lining, it offers a barely noticeable fit for continuous monitoring. Built-in sleep staging and a Recovery Score combine multiple physiological signals to deliver actionable insights for better sleep and recovery management.
Suitable for
People who want detailed sleep staging and everyday sleep scores
Users seeking accurate heart rate and HRV readings from fingertip sensors
Active individuals tracking daily activity and recovery, including steps and active minutes
Anyone preferring a low-profile, lightweight wearable for 24/7 use
When it may not be suitable
The Ultrahuman Ring AIR is not suited for users who require continuous GPS-based outdoor tracking or detailed workout tracking that depends on a wrist device with a built-in GPS. It may also be unsuitable for people who prefer a larger display or those who cannot wear rings for medical or comfort reasons.
