Ultrahuman, a young company aiming to make its mark in the smart ring market, has introduced its latest product, the Ultrahuman Ring Air. This smart ring is touted as the lightest on the market, offering health and activity tracking features typically found in a smartwatch but in a less obtrusive form factor.
The Ring Air’s most impressive feature is its size. The review unit, a size 9, is 2.5mm thick, 8.1mm wide, and has an internal diameter of 21mm. It weighs a mere 3 grams, making it lighter than most smart rings on the market. Despite its slender profile, the Ring Air looks like a regular ring, a bonus for a first-generation smart gadget.
The Ring Air is devoid of buttons, notifications, or media controls. Instead, it houses a PPG optical sensor for heart rate and blood oxygen saturation measurements, a 6-axis motion sensor, and a skin temperature sensor. This passive wearable gathers data and relies on a smartphone app to present the information to the user.
Ultrahuman asserts that the finger is a better source of heart rate and blood oxygen saturation data due to its higher perfusion index and proximity to key arteries. The Ring Air is also less obtrusive than a smartwatch for sleep tracking.
The Ring Air comes in various colors, including Raw Titanium, Aster Black, Matte Grey, Bionic Gold, and Space Silver. It is water-resistant up to 100m, making it suitable for showering, swimming, and diving. However, users should be careful as the ring may slip off.
While the Ring Air takes some getting used to, especially for those unaccustomed to wearing jewelry, it offers a unique experience. It interacts with everything you touch and does throughout the day, requiring some adjustments like removing it when cooking, washing, or working out.
Despite its impressive features, the Ring Air may not be ready to replace wrist wearables just yet. However, it certainly offers a promising glimpse into the future of wearable technology.
