Ultrahuman’s latest leap: The Ring Air

The smart ring arena is buzzing with increased competition. The most recent contender is the Ultrahuman Ring Air, a brainchild of a startup from Bengaluru. Touted as the world’s lightest sleep-tracking device, it tips the scales at only 2.4 grams. This is a clear demonstration of Ultrahuman’s commitment to breaking technological barriers while prioritizing the comfort of users.

Don’t be surprised if the name sounds familiar. Ultrahuman launched their first smart ring offering in the latter part of last year. They have a few other products in their range. As far as their first generation smart ring, that one has received mixed reviews.

Now the company has released an updated version of the original. It comes with some interesting functionality.

Ultrahuman Ring Air – what you need to know

Engineered with a durable shell made of fighter jet-grade titanium and reinforced with tungsten carbide, the tiny device is built to withstand the rigours of daily use. Its hypoallergenic epoxy resin inner coating ensures comfortable long-term wear, making it a wearable truly designed for the everyday user​.

The smart ring provides a wide range of features. The device’s Sleep Index spits out an in-depth analysis of sleep health, including sleep duration, resting heart rate, and restfulness, offering valuable insights into sleep quality. Ring Air further boasts a non-contact skin temperature sensor that tracks physiological responses to factors such exercise, stress, and illness, keeping users informed about their body’s conditions in real-time​.

A standout feature of the gadget is its use of a Phase Response Curve (PRC). This innovative tool maps the effects of various external stimuli such as light exposure, food, and physical activity to the body’s circadian rhythm. The resultant data provides users with a unique and holistic understanding of their body’s responses, empowering them to make informed decisions about their lifestyle and health​​.

The Ring Air also encourages an active lifestyle through its Movement Index. This metric is designed to optimise glucose metabolism and boost non-exercise energy usage. Moreover, it provides Heart Rate Variability (HRV) insights, a critical metric for understanding the body’s recovery capability and readiness for each day​.

As you’d expect, the ring doesn’t have a screen. So you’ll need to use the smartphone app to check your data. But its small, simple design is great for those who don’t like wearing smartwatches. The company sees the lack of a screen or vibrations as a good thing because it means fewer distractions.

Integrating with smartphones via Bluetooth Low Energy, the Ring Air can last up to 6 days on a single charge, This offers users the convenience of long-term wear without the need for frequent recharging.

Like its predecessor, the device is also compatible with the Ultrahuman M1, providing users an even more detailed look into their metabolism and health​​. This is the company’s conventional glucose monitoring platform, in case you were wondering.

Price, availability

The Ultrahuman Ring Air is available for a suggested retail price of $349 / £280 / €325 (check price on Amazon). View on manufacturer’s website.

The company is also offering trade-in options for the earlier Ring and the Oura Gen 2 and Gen 3 rings. This should make the transition to this new technology smoother for existing users. The device comes with no annoying subscription fees attached.
