Fitbit smartwatches are known to help you track your cycling time, running time, and your workouts, but they can also help you keep tabs on what is happening when you are asleep. 

All of the current Fitbit models can track your sleep if you wear them at night. If you are a Fitbit Premium subscriber, you will get personalized insights and recommendations about how to improve your sleep, and a sleep score. 

If you have Fitbit Sense, the Fitbit Versa 3 or the Fitbit Premium, you can access snore detection that detects snoring and other noises at night, according to Android Authority.

But how exactly does sleep tracking work?

Fitbit's Sleep Tracking Feature

Before you go to sleep, you need to set up the device and connect it to your phone. To do this, you need to wear it when you turn in for the night, and the wearable device will automatically detect when you doze off and when you wake up. 

If you are a Premium subscriber using a Verse 3 or a Fitbit Sense, you need to check the snore detection feature in advance.

From the main screen in the wearable app, tap the sleep entry on the list, then tap the cog icon in the top right corner. Make sure that Detect Snoring is turned on so you can see this feature. 

Remember that listening for noises uses more battery, so it is best that your smartwatch has at least a 40% charge remaining before you sleep. 

From the same screen under the cog icon, you can set your sleep goals, and have the app remind you when it is time to turn in for the night based on the bedtime and wake up times that you have set. 

What to Do After Waking Up

As soon as you wake up, your Fitbit will register that you're awake and immediately stop tracking your sleep.

On the main screen of the app, you can scroll down to see how much sleep you got, and you will see a breakdown of the different stages such as REM, light and deep. 

If you wish to see more details, just tap on the list. 

You will see a full chart showing what times you were in each stages of sleep, helping you spot spells of restlessness. You can also look back on 30-day averages, as well as common ranges for those who match your gender and age. 

If your Fitbit can measure blood oxygen saturation, you will see how this fluctuated over the course of the night. 

The Fitbit rounds up several metrics such as stages of sleep, movement and heart rate into one overall sleep score. It rates the quality of your sleep when all of the measurements have been finalized, according to TechCrunch.

Your sleep score will be broken down into several sections including restoration, which is a measure of how recharged your body should be after you've slept. 

If you want a more accurate sleep score, it is best to sign up for a Premium subscription.

According to CNET, it includes more factors such as audio and video workouts, option to invite friends, and tailored fitness goals.
