Product Overview

The Ring Air Size 13 Aster Black tracks sleep, heart rate, movement, and skin temperature for discreet wellness monitoring.

Designed for everyday wear, this Ultrahuman fitness tracker fits snugly on the finger and is comfortable overnight, making it suitable for users who prefer passive health tracking without a display or app alerts. Its fixed size 13 ring cannot be adjusted, so choosing the right fit is important for reliable sensor contact.

The ring pairs with iPhones running iOS 15 or later and Android devices running Android 6 or later via Bluetooth v5.0. Its battery lasts 4 to 6 days on a full charge, and it is water resistant up to 100 meters for up to 12 hours, allowing for showering and sleep tracking without removal. The outer shell is made from fighter jet grade titanium reinforced with tungsten carbide carbon coating, while the inner surface uses medical-grade hypoallergenic epoxy resin.

Model 170110 in black comes with a 1 year manufacturer's warranty.

At a glance

The Ultrahuman Ring Air is a premium smart ring for people who want subtle, screen-free tracking of sleep, recovery and daily movement. Its light titanium build, overnight comfort and up to 100 m water resistance make it easy to wear continuously. It is especially well suited to passive wellness monitoring, though the fixed size 13 ring is not adjustable and correct sizing is important.

Q: How do I know if size 13 will fit properly?

A: This ring is a fixed size 13 and cannot be adjusted after purchase. It needs a snug fit for reliable sensor contact, so buyers between sizes or with fingers that swell through the day should choose carefully before ordering.

Q: Will this ring work with my iPhone or Android phone?

A: Yes. Ultrahuman Ring Air pairs with iPhones running iOS 15 or later and Android phones running Android 6 or later over Bluetooth v5.0. It is a ring-only tracker, so phone compatibility matters for setup and viewing your tracking data.

Q: Does the Ultrahuman Ring Air have a screen or notifications?

A: No. Ultrahuman Ring Air has no display and is designed for passive tracking rather than on-ring alerts. That suits buyers who want discreet wear overnight, but it will not replace a watch-style device for glanceable updates.

Q: Can I wear this ring in the shower or pool?

A: Yes. Ultrahuman Ring Air is water resistant up to 100 metres for up to 12 hours, so showering and regular swim sessions are within its stated use. It is still a wellness tracker ring, not a display device for in-water readouts.

Q: Is this ring suitable instead of a sports watch?

A: It depends on what you want to track. Ultrahuman Ring Air suits sleep, heart rate, movement and skin temperature monitoring, but it does not offer the advanced sport-specific analytics buyers usually look for in training-focused wearables.

Q: How often does the Ring Air need charging?

A: Ultrahuman Ring Air lasts 4 to 6 days on a full charge. Battery life varies with use, but the main trade-off is that this model focuses on discreet all-day wear rather than adding a screen or frequent interactive features.
