You can quantify just about every part of your life with today’s tech, but what’s more important than getting enough rest? There are now a plethora of ways to keep an eye on the quality of your sleep as well as how much you’re getting.

While we’ve not been able to play around with all of these gadgets at the Gizmodo office, you shouldn’t have to look too far on the web to find reviews from current users, which will help you make a choice. Where we had the chance to test out a device, you’ll see it mentioned it in the text.

Plus. for reasons of brevity we’ve counted out smartwatches, but don’t forget the likes of the Apple Watch, the Moto 360, and just about every other model on the market that can track your snoozing as well as telling the time — provided you don’t mind going to bed each night with a watch strapped to your wrist.
