Popular Science: Fitbit smartwatches are most often associated with tracking cycling, running, and workouts at the gym—but they can also keep tabs on what’s happening when you’re much less active, like when you’re asleep.
You won’t need to do much preparation to get your Fitbit to track your sleep. Assuming you’ve already set up the device and connected it to your phone, all you’ll have to do is wear it when you turn in for the night—the wearable will automatically detect when you doze off and when you wake up.
One setting you might want to check in advance, if you’re a Premium subscriber using a Versa 3 or a Fitbit Sense, is the aforementioned snore detection. From the main screen in the Fitbit app, tap the sleep entry on the list (it will be labeled with how much shut-eye you got the previous night), then tap the cog icon in the top right corner. Make sure Detect Snoring is turned on if you want to use this feature.
Bear in mind that listening for noises uses more battery, so Fitbit recommends that your smartwatch has at least a 40 percent charge remaining before you go to bed. From the same screen under the cog icon, you can set your sleep goals and have the Fitbit app remind you when it’s time to turn in for the night (based on the bedtime and wake up times you’ve set).
