Wearable technology has evolved from simple pedometers that could only count steps to the most sophisticated technologies that can track everything health and fitness.

And these days, we have the best Fitbit for sleep tracking that you can use to assess the quality of your nap every night.

These Fitbits have altimeter sensors located just below the band to make contact with your skin.

Once activated, the device records your sleep, usually in stages, and keeps the stats in your Fitbit’s account accessible via the app.

To be clear:

These sleep trackers aren’t perfect yet, because the technology is still evolving.

But they give you data that you can rely on to evaluate the quality of your sleep. Which, in turn, goes a long way to help you re-evaluate your sleep schedule.

With that said, below are Fitbits that you can get right now and start tracking your sleep tonight.

Best Fitbit for Sleep Tracking Reviews

1. Fitbit Sense

The Fitbit Sense is the latest version in the brand’s fitness tracker series. And it’s a more improved model than what we’ve had since 2007.

It does a decent job on sleep tracking, allowing you to see your light, deep, and REM sleep in a graphical presentation.

The model includes a built-in SpO2 sensor, which monitor blood oxygen saturation.

A higher variation in your oxygen level indicates that you have a breathing issue. And a record below the range signifies that you’re fine.

Fitbit Sense requires a SpO2 Signature clock face to track oxygen saturation. You can download it from this gallery and activate it every time you go to bed.

Sense even gives you your breathing rate while you sleep, with anything between 12 and 20 breathes per minute treated as completely normal.

In the app, you can see your sleep’s stats in graphical format for all the stages throughout the night. Additional stats include oxygen variations and sleeping heart rate.

It’s even more interesting that Fitbit Sense can monitor how many times you toss and turn in bed. Then, it displays the data in percentage formant.

2. Fitbit Versa 3 Health and Fitness Smartwatch

Fitbit Versa 3 gives you the metrics you need to evaluate the quality of your sleep every night. And it does do quite well than Apple, Samsung, Garmin, and Letscom watches.

With easy to read data presented in richer graphical chart and clear to read text, you get more insights about your sleep every day.

Beyond recognizing the time you go to sleep and the time you wake up, Fitbit Versa 3 monitors your sleep in stages, with scores assigned to each stage in the mobile app.

Fitbit integrates the SpO2 sensor in this model.

While the pulse oximeter lets you determine whether you have breathing issues, there’s no strong evidence to support its ability to determine if you have sleep apnea.

Perhaps the biggest downside with the Fitbit Sense so far is that restless and sleeping heart rate data is available only to premium members. But you can still get some few insights on the same.

3. Fitbit Charge 4 with Built-in Sleep Tracking

Fitbit has been helping people track sleep ever since the debut of the original Charge. But since Fitbit Charge isn’t as robust, an upgrade was necessary.

The fourth edition of the Charge series is no doubt a refined device. And its ability to monitor light, deep, and REM sleep makes it one of the best Fitbit for sleep tracking.

With Charge 4, you don’t need the app to see most stats. You can see data such as sleep score and mode right from your wrist.

Swipe up the clock face for sleep score or long press left button and swipe right to see sleep mode.

Sleep score isn’t a metric by itself, though. It’s the quality of your sleep based on time spent awake and asleep, deep and REM sleep, restlessness, and sleeping heart rate.

Charge 4 measures sleep scores in range, with a value under 60 representing poor sleep.

You can connect Charge 4 to the app to see more sleep data presented in easy to read graphs. You can use this information to optimize your sleep properly.

Fitbit Charge 4 also includes an estimated variation. While the value will fluctuate from time to time, a higher variation is a possible sign of breathing issues.

4.  Fitbit Versa 2 Health and Fitness Smartwatch

Using motion detection, heart rate data, and an array of sensors, the Fitbit Versa 2 smartwatch gives you the information you need to evaluate the quality of your sleep every night.

Like Charge 4 and the latest Sense, the Versa 2 displays your sleep in stages, letting you know your light, deep, and REM sleep.

The model begins to track sleep the moment you go to sleep and stops when you wake up. It collects data in between and displays them in charts.

Furthermore, Fitbit Versa 2 takes the data and uses it to present Sleep Score.

The score is important because it not only helps you to understand the quality of your sleep but also makes it easy for you to optimize and personalize your sleep schedule.

5. Fitbit Inspire 2 Health and Fitness Tracker

When it comes to sleep tracking, the Fitbit Inspire 2 uses a built-in accelerometer to monitor and evaluate the quality of your sleep right off the bat.

It uses an optical heart rate sensor to detect if you’re asleep or wake. So you get reliable stats that you can use to evaluate and improve the quality of your sleep.

You’ll love this version because it automatically enters the sleep-tracking mode and does its job well. There are no buttons to press and no settings to customize. Just go to bed and let the Inspire 2 do its job.

By breaking down your sleep in stage, you’re able to know how any hours you spent in light, deep, and REM sleep.

This sleep tracker uses the information to give you a sleep score, with a range between 80 and 90 indicating better sleep anything below 60 indicating poor sleep.

Although the Inspire 2 can monitor your restlessness and sleeping hear rate, you’ll need a premium subscription to get the data.

While the built-in alarm won’t work well for the deep sleepers, it produces a gentle vibration that can wake you up just in time to get ready for the day.

6.  Fitbit Charge 3 Fitness Activity Tracker

Although Charge 4 is the new kid on the block in the Charge series right now, Fitbit Charge 3 still does a pretty decent job in terms of sleep tracking.

With this, it’s not just about how many hours you’ve had a nap. The version goes even deeper into analyzing the quality of your sleep so that you can personalize your bedtime schedule.

Just like Charge 3 and Sense, Fitbit Charge 3 includes the SpO2 sensor, which measures blood level and sleep patterns. Not to mention it can go a long way to detect sleep apnea.

Don’t mistake it for being bulky, because, despite its size, Charge 3 is lightweight and easy on your wrist. Just wear it properly so you don’t have to worry about wrist pain from wearing a Fitbit.

To get the most out of Charge 3 while sleeping, it’s best to turn off the notification and the wake screen. Otherwise it might wake you up and disrupt your sleep.

Speaking of analysis, Charge 3 gives you a graphical presentation of your sleep in stages. You can see your light, deep, REM, and awake time.

7. Fitbit Inspire HR Fitness Tracker

The Inspire HR is one of the waterproof Fitbits that can also track sleep, and it does so really well.

Designed to start tracking right from the moment you go to sleep, the Inspire HR doesn’t require any pre configuration to do its job.

Not only does it track your movement when you’re asleep, it also monitors your sleeping heart rate to give you an accurate estimate of the time spent in light, deep, and REM sleep.

Fitbit Inspire HR monitors sleep in two modes. And I think that what you choose depends on what you’d like to achieve.

It’s in normal mode by default. In this case, the device treats awake and restless time as the major movements.

However, if you need something a lot more in-depth, consider switching to the sensitive mode. It’s a good option for registering all movement, allowing you to get a clear picture of the quality of your sleep.

By tracking your movement patterns, the Inspire HR is able to determine your awake and restless state, with many movements giving you a terrible sleep score.

Fitbit Inspire HR includes a bedtime reminder, and this can be quite helpful in developing a better sleeping pattern. Still, I don’t think you’ll use it if you just want to measure the quality of your sleep.

8.  Fitbit Alta HR

The concept of tracking sleep with the Fitbit Alta HR is more or less the same with the models above.

It uses an accelerometer to track your movement. Then, it combines the results with your heart rate’s data to determine your sleep’s stage.

And while the tracker won’t be 100% accurate all the time, and you shouldn’t expect it to be anyway, you do get a reasonable estimate that gives you insights into light, REM, and deep sleep.

Not to mention it can even detect the time you wake up.

With the Alta HR, you get a presentation of how your body was moving. Given that the data is in a graphical format, it’s quite easy to understand.

In the app, you can see how much time you spent in each sleep stage. And you can use this information to customize your bedtime schedule.

To be clear, it’s not exactly a health issue if you don’t get the best sleep score. Sometimes it’s your cat’s purr or baby’s crying noise that distracts your sleep.

Keep in mind that the early days of wearing the Alta HR may not exactly be the time to expect consistent results from the sleep-tracking feature.

And while this is a problem Fitbit should fix, the best solution at the moment is to let the Alta HR learn more about you and your bedtime routine.

The watch’s vibrating alarm offers a smooth sensation, and it’s a good one to use if your partner’s wake up time differs from yours.
