The Best Sleep Tracker Devices to Help You Get a Good Night’s Sleep


The Best Sleep Tracker Devices to Help You Get a Good

Sleep is essential. Not getting enough sleep makes our memories worse. Our attention spans are shorter, we become more irritable, and we have less energy. We also make worse decisions when we’re tired.

Not getting enough sleep increases our risk of developing cardiovascular disease, mental health disorders, diabetes, obesity, etc. People who are not well-rested are more likely to die than those who get enough sleep.

People need good sleep every night. People know if they are getting good sleep by how they feel in the morning. If people go to bed early but feel groggy and irritable, they do something wrong.

Sleep trackers are devices that measure different aspects of our sleep. They can be worn as rings or watches, or they can be placed under our mattresses.

No matter where you put your tracker, what’s important is what it is tracking. Some apps that track movement are not suitable for tracking sleep quality. Devices that measure heart rate and skin temperature are more accurate.

Let’s look at some of the best sleep tracker rings, watches, and tracking pads.

Quick Picks:  The Best Sleep Tracker Devices to Help You Get a Good

Oura Ring

One of the best wearable sleep tracking technologies is the Oura Ring. It uses your finger to assess your heart rate and variability. And it is the most effective sleep tracker available. It uses your finger to measure your heart rate and how it changes. A watch or necklace, for example, can provide a more precise reading.

The device measures skin temperature. It can show when someone is stressed, ill, or on a period. It adapts to each person, giving different people different advice and alerts based on what is normal for them.

Oura tracks your sleep data and how well you sleep. It also keeps track of how active you are. This information is used to create a readiness score for each day. The readiness score lets you know how prepared you are for different activities on that day.

The ring should snugly fit over your finger. Oura will give you a complimentary size kit if you purchase the ring. Although the ring is small, it has long battery life. Depending on the size of the ring, charging it from empty takes 60-80 minutes.

The Apple Watch is water-resistant up to 100m, so you don’t have to take it off for regular activities like bathing, washing your hands, doing the dishes, or swimming.

With the Oura monthly membership program, you can access detailed data and custom recommendations. You will also be able to do guided sessions such as meditations. After you finish a session, you will receive data on how your body responded to it.

If you want to use the Oura ring to its full potential, you need a full membership. If you make your first purchase, you will receive six months of membership for free.


  • Elegant design
  • More accurate than the majority of sleep monitors
  • Skin temperature, heart rate, and variability are all measured.
  • 100m water resistance
  • Adapts to the person wearing it


  • Expensive
  • Requires an ongoing subscription to make the most of the device

Go2sleep Ring

The Oura ring is expensive. If you want a less expensive option, we recommend the Go2sleep ring. It costs about one-third of the Oura ring and tracks heart rate and blood oxygen levels.

Vibration feedback will let you know if you have any health problems during sleep. You can see this data and learn more about your health on Windows PC, Mac, iOS, and Android devices.

The Oura ring is a device that you wear on your finger. It uses data from you to create a daily readiness score. This score can help you figure out the best time for exercise or focused work. The battery usually lasts for three nights, and it charges in around two hours using the included magnetic charger.

The lightweight silicone ring only weighs six grams. It is water-resistant and includes a handy “find ring” option if you ever lose or misplace it.

The Go2sleep does not have the same sleek design or fancy features as the Oura, but it is much cheaper and still tracks your sleep (and other health metrics). For many people, this is a good trade-off.


  • Comparatively low cost
  • Lightweight
  • Measures HRV, resting heart rate, and SpO2


  • The design isn’t beautiful.

Fitbit Sense

The Fitbit Sense is currently the best wrist-based sleep tracker available. Heart rate, blood oxygen levels, and skin temperature are all monitored. It also contains a stress manager and an electrodermal activity tracker, which uses minute electrical changes on the skin to evaluate stress levels.

The daily readiness score is based on a combination of factors. This number tells you how prepared you are for the day. The battery lasts for six days or more. It only takes 12 minutes to charge the battery fully. Plus, the built-in microphone can track snoring.

The Fitbit Sense has several features in addition to sleep tracking. These include activity tracking with a built-in GPS and Google Assistant and Amazon Alexa support. The Sense is also water-resistant up to 50 meters, meaning you don’t have to worry about rain, dishwashing, or swimming.

The Fitbit app is available for both the iOS and Android platforms. It provides a lot of helpful information in an easy-to-read way. The Fitbit Premium subscription is also available, costing $9.99/month or $79.99/year after a six-month free trial.

The standard app has enough features for most people. However, if you want more features, you can buy a Premium subscription. It will give you access to advanced sleep tools, personalized insights, customized health programs, mindfulness content, and video workouts.


  • High-end features
  • Fast charging
  • 50m water resistance
  • Well-known brand


  • Somewhat expensive

Fitbit Charge 5

The Fitbit Charge 5 is a cheaper alternative to the Fitbit Charge 6. Heart rate, blood oxygen (SpO2), electrodermal activity, skin temperature, and Charge 6 are all monitored. It gives you proper sleep and health insights.

The Charge 5 is the more expensive model, but it doesn’t have some features. These features don’t affect sleep tracking. The Charge 5 features a built-in GPS for running, hiking, and biking, and it can swim up to 50 meters.

The battery on the Fitbit Charge 3 will last up to seven days. It will take anything from one to two hours to completely charge the battery. In addition to the standard Fitbit app, you can also view your data in Fitbit Premium. It provides additional insights, guidance, mindfulness content, and workout videos.

The Charge 4 is a good choice for a sleep and activity tracker if you don’t need the smartwatch features of the Sense. It is from a well-known brand, so you can trust that it will work well.


  • Reasonably priced
  • Good sleep and activity tracking
  • Well-known brand


  • Missing some of the higher-end features of other Fitbit models

Withings Sleep

If you don’t want to wear a wearable, the Withings Sleep is a good option. This flat pad sits under your mattress and tracks sleep cycles and heart rate. Snoring and other breathing problems, such as sleep apnea, can also be detected.

The pad is compatible with many mattresses, including spring, latex, foam, and memory foam mattresses 4-15 inches high. It doesn’t need to be charged; instead, it plugs into a wall outlet using the USB power adapter.

You can see your data and recommendations on the Withings Health Mate app, available for Apple and Android devices. If This Then That (IFTTT) can be used to control other smart devices, such as bedroom lights or thermostats, using the tracking pad.

Even though it’s helpful to track snoring and sleep apnea, it’s nice that you don’t have to wear or charge the sleeping pad. The other sleep data isn’t as accurate as data from a device that rests against your body.


  • Snoring and sleep apnea are monitored.
  • Reasonably-priced
  • It’s not necessary to remember to charge.


  • Measurements aren’t always as precise as with a wearable device.

Best Sleep Trackers

Sleep is essential for maintaining health and happiness. If you’ve been feeling tired lately or don’t feel like you’re getting enough rest, you might need a sleep tracker. We’ve gathered the best sleep trackers available on the market. Let’s get started!

  • No need to wear anything
  • Discreet sleep tracking
  • Sleep Apnea detection


  • No smart features
  • One tracker per person

7. Biostrap Evo

Biostrap is a technology that uses different biometric measurements to track how well you sleep. This includes tracking your heart rate, variability, oxygen saturation, and respiratory rate.

This device doesn’t measure skin conductance or temperature. It only collects data samples every two minutes if you pay a monthly fee. The sampling frequency is even lower if you don’t have a membership.

Another thing that might be a problem for some users is that you have to take the strap off to charge it every day. The battery only lasts for 10 hours if you turn on “Max Biometrics.”


  • Monitors heart rate, heart rate variability, oxygen saturation, and respiratory rate
  • Monitors your snoring intensity
  • Several characteristics are supported by validation studies.
  • I performed fairly accurately on tests.

This Alexa-enabled tracker has advanced sensors and a best-in-class AI that accurately analyzes your sleep state. And offers personalized coaching to help improve your sleep in the future. We also loved the integrated app, which was easy to understand and filled with useful and interesting information.

This smartwatch is good for tracking sleep quality, but it needs to be plugged in. Make sure your bed is close to a power outlet. This product also tracks sleep quality, but it doesn’t track breathing as our third pick does.


  • Works with all mattress types
  • Offers individualized sleep coaching
  • The intuitive app is easy to understand


  • Must be plugged in
  • Does not monitor breathing

The Most Important Features to Consider

  • Tracker Type

Sleep trackers usually come in two different types. Some slide underneath your mattress and above the box spring, and there are smartwatches. Sleep trackers that slide underneath your mattress usually have more information about sleep, and they can also track your breathing. Some watches can track how you sleep. They track how long you sleep, how well you sleep, and if you snore. But some watches also have fitness tracking abilities. They can track your heart rate and how well you integrate with your smartphone.

  • Integrated Apps

All of the products mentioned above can be accessed through an app on either a smartphone or computer. The apps vary in their offerings, but the majority give you access to information regarding your sleepover weeks or months. Plus, they offer advice on how to get better sleep.

These apps track more than just sleep. They can track heart rate, breathing, sleep cycles, and fitness metrics. Sleep cycle apps use the movement sensor and microphone on your phone to sense your sleep cycles. Then they give you data about your sleep patterns and sleep stages. You can use this data to learn about the different stages of sleep you go through (light sleep/deep sleep/REM sleep) and get a sleep score, plus tips on how to improve your sleep habits.

  • Durable Materials

You should ensure that the sleep tracker you choose lasts a long time. To do this, you should select a product made from durable and long-lasting materials. Many of the smartwatches mentioned above are made from aluminum alloy or steel. Some have Gorilla glass which makes them nearly indestructible.

Final Thoughts on Sleep Trackers

In recent years, sleep tracking gadgets have gone a long way. They are much more advanced than the simple movement data that you can get from your smartphone. The best sleep tracking devices give you a holistic view of how well you are sleeping and your overall health.

Look for a sleep tracker to track your heart rate (both variability and resting pulse) and skin temperature to get the most accurate data. After that, you need to decide which device is suitable for you. Consider what type of wearable you would be willing to wear daily and nightly.

There are numerous varieties of rings to select from. The Oura Ring is the ideal option if you want a ring that tracks your sleep. Fitbit Sense is a good choice if you want a watch that tracks your sleep. If you don’t want any wearable technology, the Withings Sleep pad is your best bet.

Frequently Asked Questions About Sleep Tracker Devices

Is Fitbit a Good Sleep Tracker?

The Fitbit Inspire 2 is the best Fitbit for tracking sleep quality. It doesn’t measure your SpO2 blood-oxygen level. Still, it is a great affordable activity tracker with all the sleep-quality tracking you need.

Are Smartwatches Accurate for Sleep?

Sleep devices are popular, but there is not a lot of research on how accurate they are. So far, research has found that they are not as precise as polysomnography tests – which experts use to diagnose sleep disorders. When determining whether or not a person is asleep or awake, sleep monitors are only accurate 78 percent of the time.

How Do Smartwatches Detect Sleep?

Most sleep trackers use accelerometers to measure how much movement you make while you sleep. This data is then analyzed using an algorithm to estimate sleep time and quality.

How Do Smartwatches Detect Deep Sleep?

Most sleep trackers on the market measure heart rate and movement. The idea is that because, for example, the heart slows as you move into stage 2 (deep sleep) of our four-stage sleep cycles. The body is paralyzed during REM sleep; the tracker can estimate the stage you are in.

Do I Watch Track Sleep?

If you want, you can wear your Apple Watch to bed so that it can track how much sleep you’re getting. The Sleep app will show you how much sleep you got and how your sleep has been over the past 14 days. If your Apple Watch is low on battery, it will prompt you to charge it before bed.

Can Smartwatches Detect Sleep Apnea?

At the moment, even the most advanced smartwatches and fitness trackers can only tell if you might have sleep apnea. You might have to see a doctor determine if you have obstructive sleep apnea.

Does the Oura Ring Really Work?

The Oura Ring is a useful health tracking device. However, it feels incomplete at this time. This is because you can monitor your heart rate but not your body temperature. The ring also costs $299.

How Does a Sleep Tracker Know You’re Asleep?

Most sleep trackers are watches that you wear on your wrist. They work by monitoring your body movements as you sleep. This tells how much time you spent awake and asleep. Some devices also look at heart rate changes during sleeping to estimate how much time you spend in each sleep cycle.

How Does Fitbit Know I’m Asleep?

Fitbit estimates your sleep stages by looking at your movement and heart-rate patterns. When you have not moved for about an hour, Fitbit assumes you are asleep. It also looks at how long it takes to move again after a certain period to determine if you were sleeping.

How Accurate Are Fitness Trackers for Sleep?

Sleep trackers are not as accurate as polysomnography tests in diagnosing sleep disorders. Polysomnography tests are used by experts to identify sleep disorders. Sleep trackers are only accurate 78% of the time when identifying sleep versus wakefulness. This accuracy drops to around 38% when estimating how long it took participants to fall asleep.
