Saturday night’s alright for light ring
ULTRAHUMAN RING AIR
If you like to sleep au naturel, even wearing a smartwatch to track your snoozing might feel like donning a hazmat suit before bed – but what about a ring? As it weighs as little as 2.4g (depending on which size you opt for), you’ll barely notice you’re wearing the Ring Air, but it’s definitely not lightweight when it comes to features. As well as tracking sleep it also monitors your movement, heart rate (including variability) and skin temperature, with all vital stats viewable via the Ultrahuman app. It’s water-resistant down to 100m, so you don’t have to remember to take it off in the shower or at the pool, and the battery lasts up to six days, which is long enough to cover even the most epic of naps.
