QUICK SUMMARY Hatch has launched the Sleep Clock, its new contactless sleep tracker. Priced at $249.99, the Hatch Sleep Clock uses radio signals to track your breathing, movement, sleep stages and more to help you improve your sleep. The new Hatch Sleep Clock is a contactless sleep tracker that sits on your bedside table rather than in your bed or on your body, and it offers a full sleep experience to help you sleep better. Unlike traditional sleep trackers, the Hatch Sleep Clock isn’t a wearable, and it doesn’t use microphones or cameras. The Hatch Sleep Clock is available to buy for $249.99 at Hatch .
