The Best Sleep Trackers
WiredSleep Routine: Tracker & Alarm for $7/month or $60/year : You don’t necessarily need a new gadget, because there are several sleep-tracking apps. Google Nest Hub 2nd Gen for $79: The second-generation Nest Hub uses radar to track your sleep, which means you don't need to wear anything, but it also has a microphone to track snoring, sleep talking, and other nocturnal sounds. I love the Nest Hub on my nightstand for smart home controls, family photos, and listening to sleep sounds or podcasts in bed, but the sleep tracking consistently overestimated my REM phases and missed periods of wakefulness that other trackers recorded. It’s chiefly a meditation aid designed to help you relax, but it can also track your sleep, recording your heart rate, respiration, time to fall asleep, and how much you moved around to give you an overall sleep score. The sleep tracking is limited, showing the familiar four phases, sleep efficiency, and consistency, but I often woke to find they had come off during the night and cut my sleep tracking short.
