There are plenty of devices that say they can track your sleep . . . but none of them feel all that accurate. This one does. And the only tradeoffs are $99 and letting one of the big tech companies watch you while you sleep every night.
Google's newest Nest Hub goes on sale on the 30th of this month. It'll cost $99. And its big feature is that it can accurately track your sleep by using a RADAR sensor.
You put this thing on your nightstand, and then it can measure everything about your sleep, like how your chest moves when you're breathing, what movements you make, and whether you snore or cough.
Accurate sleep data could be really useful . . . you can find out how much you really ARE sleeping and the app says it can give you recommendations to help you sleep better.
And Google swears the data won't be sent to them . . . unless you want to sync it with their health app. So use it at your own privacy risk.
