It is the so-called “celebrity ring” and Ultrahuman, an Indian company founded in 2020, is ready to stand up to it with its Ultrahuman Ring Air.
The bet is clear and transparent: a ring similar to the Oura Ring, but that does not depend on a subscription.
Ultrahuman Ring AIR
*Some prices may have changed since the last review.
Before buying an Ultrahuman Ring Air it is necessary to know the size, and the size depends on the finger. They send you a kit that includes all the available sizes and it is a matter of trying on the ones that we think will fit us best.
Design
The Ultrahuman Ring Air is a ring larger than a regular ring. It has a width of 8.1 millimeters, a thickness of between 2.45 and 2.8 millimeters (depending on our size) and a weight of between 2.4 and 3.1 grams (again, it depends on the size).
It is available in four finishes, namely black, shiny gold and silver, and matte gray, which is the one we have had the opportunity to test. The exterior is made of titanium and reinforced with tungsten carbide, while the interior is coated with hypoallergenic epoxy resin. The thing is that yes, it is resistant to daily use, but it is a ring and as such, it is exposed to bumps, friction and other hardships and yes, it is possible that, in the long run, it will end up getting a little scratched. Something that, all things considered, can happen to any wearable or any ring.
In this small ring there is an infrared PPG sensor, a skin temperature sensor, a six-axis motion sensor and green, red and infrared LEDs for heart rate and blood oxygen level. That, in addition to the battery, the Bluetooth sensor, etc.
For the rest, it should be noted that the ring has IPX8 resistance and can withstand a depth of 100 meters. It can be worn during the shower or while washing our hands and, of course, if we are diving or doing water activities. The only context in which I would be especially careful is doing an intense sport in which the ring can suffer more than necessary (such as boxing, fitboxing...) or if we are going to manipulate heavy things.
The Ultrahuman ring measures heart rate discontinuously, that is, it is not a real-time measurement because let's not forget that the device has a 24 mAh battery.
