Ultrahuman Ring Air Aster Black size 7

You won't even feel the smart ring on your hand

The Ultrahuman Ring AIR is a device of the future that continuously monitors your activity. Yet it's up to 11 times lighter than a typical smartwatch, weighing just 2.71 grams. The ring has a smooth, hypoallergenic casing, which provides you with complete comfort while wearing it, whether during sleep or sports activities. For accurate measurement of various values, the Ultrahuman smart ring is equipped with a six-axis motion sensor, a non-contact temperature sensor and a PPG cardiovascular health sensor.

Keep track of your sleep and body temperature

The built-in sensors measure not only your activity but also the quality of your rest and recovery. In the app, you can then look at the length and quality of your sleep. The Ultrahuman smart ring also measures body temperature, which is a key indicator for measuring physiological states and the body's responses to various stimuli.

The Ultrahuman Ring AIR will surprise you with its durability

Despite its miniature size and low weight, the smart ring will pleasantly surprise you with its durability and battery life. Using modern technology, the Ultrahuman Ring AIR lasts up to 6 days in continuous operation. You can recharge it on the included wireless charger. The unrivalled durability of the smart ring is provided by a robust, fighter-jet-grade titanium, which is reinforced with a layer of tungsten carbide. This is also why the Ultrahuman Ring AIR can withstand submersion to a depth of 100 metres. The smart ring is therefore just as at home on land as it is in water.
