There are numerous studies showing that the quality of our sleep affects all aspects of our health and well-being.

Moreover, on this site, I’ve always emphasized the importance of getting the right amount and quality of sleep. It has been proven, time and again, that doing so improves our mood and boosts our bodies’ ability to fight off sickness.

Recently, tracking our sleep has become widely popular.

Monitoring how long we sleep and the quality of our slumber has become almost an obsession with many people. This is largely because many wearable fitness trackers have now added sleep-tracking features alongside step counters, heart rate monitors, and food logs.

These monitors come in different forms, including bedside monitors, wearables, and non-wearables (the kind you put under your pillow or mattress).

Today, we are giving you a list of the five best sleep trackers available on the market, which provide information about your sleep cycle and how well you’ve slept during the night.

But first, let's examine the benefits of tracking your sleep, and the different kinds of sleep trackers that are available.

What Are the Uses of a Sleep Tracker?

On average, adults need seven or more hours of sleep every night. However, many are unable to meet this basic need. About 70 million Americans suffer from a sleep disorder, which is one possible reason why there is an increased interest in fitness trackers that can also monitor your sleep patterns.

Sleep trackers provide you with insight about your sleep patterns so you have a better understanding of whether or not you’re getting the right amount of sleep. If you're not, you may need to modify your pre-bedtime habits to encourage a better quality of sleep, and make sure that you are getting enough shut-eye every night.

Now, you're probably wondering, "How do sleep trackers work?" Sleep trackers work by monitoring how much you move throughout the night while you are in your bed, thereby measuring your sleep quality. Using accelerometers to track your movements, the tracker analyzes whether you’ve had a peaceful or restless slumber.

Sleep trackers can give information about how much time you spend asleep, which can alert you to possible sleep-associated issues.

There are also sleep trackers that can monitor how much time you’re spending in each stage of sleep. These trackers can then use the information to schedule your alarm to go off at a time when they detect you’re in a light stage of sleep and can be woken up more easily.

By analyzing the times you are asleep and awake, you can get information about how much time you spend being asleep, which can alert you to possible sleep-associated issues such as sleep apnea.

Some trackers can even help you create a better environment for sleeping by assessing your surroundings at night. This may include the lighting or the temperature of your room, which can have an impact on your sleep quality.

Now that you know what a sleep tracker can do for you, how do you know which one will work best for your needs? Let's look at some factors you should consider when shopping for a sleep tracker.

Your Guide to Choosing the Best Sleep Tracker

First, you need to know the purpose of monitoring your sleep. Are you using a sleep tracker because you have a difficult time falling asleep? Do you wonder if you spend enough time in the REM stage?

If you’re looking to improve the quality of your sleep based on what your tracker shows you, make sure it offers a detailed view of your night's activities in its companion app, including your sleep duration, quality, stages, and external factors. 

Look for sleep trackers that have the ability to analyze your sleep environment so you can check for patterns in the results to pinpoint some possible causes of your sleep issues. It could be that there is too much light or noise around you and those things are keeping you up at night. If it is a simple fix to get more sleep, it is definitely worth knowing the causes of your struggles.

You may also want to choose a less cumbersome design. Since you will literally be going to bed with this device, make sure that the design is not large or heavy, especially if it’s a wearable device.

Even with a non-wearable sleep tracker, there will be some element that is around you, which could make you aware of its presence. You may not be able to fall asleep if you are wearing something that is especially bulky.

Make sure your sleep tracker comes with a companion app. This way, you can customize the settings according to your sleep-tracking needs. You will also be able to see a more detailed and extensive explanation of your sleep.

You can view your data and, often, the progress that you are making toward your sleep goals (if your tracker can monitor both). You will usually find other benefits that come with the companion app, such as features to engage with other people using the app so you can keep each other on track, as well as rewards for reaching your goals.

In choosing the best sleep tracker you need to know the purpose of monitoring your sleep.

It is also best to have a sleep tracker with syncing capabilities. By having a tracker that can sync with all of your tech gadgets (like your smartphone and tablet), you will be able to have easier access to the data about your sleep habits.

Finally, you will want to consider the price. In addition to knowing your goals, it’s equally as important to know your budget. The majority of sleep trackers range anywhere from $50 to $300, typically increasing in price depending on the number of features that they offer.

If you are looking for a comprehensive tracker that will give you a wide range of advanced features, including automatic sleep detection, a smart alarm, and a heart rate monitor, it will probably be more expensive than some of your more basic trackers.

However, if you want to be able to track your sleep and activity for a long period of time, it may be worth it to spend some extra money to buy a tracker that meets your needs. However, it is important to remember that just because a tracker is expensive doesn't always guarantee that it will have better performance. Likewise, a more affordable product is not always low in quality and features.

Now let's look at some of the best options that are on the market today.

5 Best Sleep Trackers

1. Fitbit Charge 2 Heart Rate + Fitness Wristband, Black

Despite the fact that this product has been on the market for a while, it remains the best overall option because of its various features and high quality—especially if money is not an issue for you. This sleep tracker measures and records the amount of time you spend awake, as well as your light, deep, and REM stages of sleep. Plus, it is one of the most consistent trackers on the market, which is key because you can be sure that the results you see every morning are correct.

This sleep tracker gives you the needed guidance and coaching to get a better night's sleep. It continues to add new insights to keep it up-to-date and competitive with other products on the market. The sleep stages feature provides you with a helpful breakdown of your sleep phases, as well as a benchmark against other users in your demographic.

The Fitbit Charge 2 also comes with a wearable design, which is an added bonus. Its battery life is about five days, which is good compared to other options. It has a black-and-white OLED screen that allows you to adjust the brightness.

You can easily read this screen outdoors if you are using this tracker for fitness purposes as well as sleeping. The display activates when you rotate your wrist to look at it, which conserves its battery life. Because it is not water resistant, you do need to take it off when you get in the shower.

You have three size options for the interchangeable band, so this sleep tracker will fit most users. It has a large display, allowing you to see the information on it easily whenever you glance down.

PROS
  • Comfortable to wear.
  • Offers reliable information.
  • Measures stages of sleep.
CONS
  • Relatively expensive.
  • Does not have a GPS function.
  • Gesture recognition sometimes does not work.

This option is the best affordable sleep monitor and wearable fitness tracker for every member of the family. It is a highly adaptable piece of technology that is great for everyone. You don’t have to have a gym membership to benefit from wearing this tracker, as there are a lot of variables that it keeps track of during the day. The main purpose of this product is to inform users about a wide variety of statistics about their everyday life to help them improve their overall health.

There are several unique and useful features included with the Letsfit Fitness Tracker. It offers a heart rate monitor, sedentary alerts to let you know when you should get up and move around, multiple sport tracking options, and smart notifications that remind you of important events, send notifications about texts and incoming calls, and provide you with social media alerts without you having to get out your phone.

And, of course, it offers sleep monitoring software that will keep track of and record the different stages of sleep that you go in and out of, based on your heart rate. It will also let you know how many times your sleep is disturbed and how often you wake up. This will give you all of the information that you need to know, whether you think you are getting a good night’s sleep or not.

Another benefit to this sleep tracker is the fact that it is waterproof. While you probably don't want to take it swimming, you don't have to worry about any damage happening if you wash your hands with it on.

This sleep tracker is available for a small percentage of the price of some high-end fitness trackers, but it offers all of the same things, making it a valuable device. It is constructed with the everyday user in mind, meaning it is both durable and easy to use.

PROS
  • Great for men, women, and children alike.
  • Affordable option.
  • Syncs with a helpful app.
CONS
  • Some users question the accuracy.
  • Uses a 24-hour clock, which is confusing for some users.
  • It is hard to change the time zones on this device.

This product features 14 different sports modes to choose from, making it a versatile option for anyone who also wants to use the fitness features. Its simple, low-profile design allows users to wear this tracker every day with any type of outfit. It also makes it easy to sleep in since it is not bulky or cumbersome.

This product comes with a mobile app, called VeryFitPro, which has a professional look to it. The app can connect to Google Fit, meaning if you wanted your workouts and sleep to sync with MyFitnessPal, you can easily do that. Many products in this price range do not have this capability.

The watch and strap are lightweight and comfortable. You can easily wear this sleep tracker all day and night without noticing it. There is really no learning curve once you get this watch either, and the app is of a high quality.

PROS

CONS
  • The heart rate monitor is inconsistent.
  • The app uses a lot of phone battery.
  • Difficult to keep connected to Bluetooth.

This option is the best non-wearable product that tracks your sleep quality and provides precise data from your sleep cycle. The company behind this product promises to provide you with the tools you need to understand the quality of your sleep every night, and how you can improve it.

The Beautyrest Sleeptracker has three parts to it: a central processing unit that plugs in and remains near your bed, two movement sensors that you put between your mattress and your box spring that plugs into the CPU, and an app for your smartphone.

The movement sensors are about a quarter inch thick, and they are surrounded in high-density foam, making them undetectable when you are asleep. As long as your mattress is at least a queen size, these will track the sleeping patterns of two sleepers, and they can tell the difference between the two people, so you don't have to worry about your movements interfering with your partner’s.

It is quick and easy to set this sleep tracker up, and, once it is installed, it is essentially invisible. The sensors have adhesive backings, ensuring that they stay in place. The CPU connects to your Wi-Fi to upload each night’s data to its servers, which then generate reports that you can see in the app and also have emailed to you.

This tracker gives you an accurate sense of the quality of sleep you got the night before in terms of the three main types of sleep: light, deep, and REM. Each morning, within one hour of the last person getting out of bed, you can view your sleep report, which will tell you your sleep score out of 100.

This score is found by combining your total sleep time with the amount of time you spent in each stage of sleep, in addition to factors such as the number of times you woke up during the night. While getting a perfect score of 100 would be great, scoring 80 or higher means that you got very good quality sleep that night.

The app even asks you questions such as how stressful your day was, if you exercised, or if you consumed alcohol or caffeine, which are all factors that can impact the quality of your sleep. After gathering this information over a period of time, the app can make connections between your daily habits and the quality of sleep you are able to get.

PROS
  • Offers precise data about your sleep cycles.
  • Can be used by two people.
  • Gives you helpful facts about the impact of your lifestyle and environment on the quality of your sleep.
CONS
  • Expensive when not on sale.
  • If you get in bed, it assumes you are asleep. It cannot distinguish from when you are awake but lying still and when you are sleeping.
  • Some users have a hard time connecting it to Wi-Fi.

This is the best option for its design and price. It comes equipped with the latest HR sensor to ensure accurate heart rate monitoring. It also offers a multi-sports mode, so you can get accurate results if you use this tracker when you exercise.

You can automatically track your sleep quality with this device, as it detects your sleep and analyzes your sleep quality from 9:00 pm to 8:00 am. It can detect when you are in a deep sleep and a light sleep, or if you are awake. It also allows you to set an alarm to wake you up using silent vibration, which is smooth and comfortable.

PROS
  • Waterproof.
  • The band plugs directly into a USB charger, so you do not need a cable.
  • Alerts you when you have an incoming call.
CONS
  • Some users find the screen to be too small.
  • Not completely accurate.
  • Screen scratches easily.

Conclusion

Before wrapping this up, we have to mention that there are no consumer sleep tracking devices on the market that can measure your quality of sleep as accurately as polysomnography, which is what doctors rely on to diagnose serious health conditions that are related to sleep, such as sleep apnea.

Polysomnography is performed in a sleep lab, under highly controlled conditions. It requires users to have sensors attached all over their bodies. While it is uncomfortable, it is still the gold standard for measuring sleep on a medical level.

If you suspect that you might be suffering from a serious sleep disorder, you should not rely on a consumer-grade device. Rather, you should seek professional medical advice.

However, there is a huge gap between achieving high-quality sleep and suffering from a serious condition such as sleep apnea—and most of us fall somewhere in the middle.

We wake up in the morning still feeling groggy and tired, but we can still drag ourselves out of bed. It’s this need that these products fill, by offering you a snapshot of how you slept so you can experiment with some modifications to your lifestyle, such as going to bed earlier, avoiding caffeine after lunch time, or getting more exercise.

That said, all of the sleep trackers reviewed today are top performers in their categories and can offer you a wealth of information that can improve your sleep and overall quality of life. However, the standout product in today’s review is the Fitbit Charge 2 Heart Rate + Fitness Wristband for its features and quality.
