If you're facing problems in getting enough shuteye, tracking could help you better understand your sleeping patterns and work to improve the quality of your sleep.
Sleep trackers come in all shapes and sizes, from wearables to devices you keep on your bedside table. With years of testing mattresses and sleep products under our belts, we've used our experience to assess the top sleep trackers available right now.
What is the best sleep tracker?
The best sleep tracker is the Whoop 4 Band, thanks to its in-depth sleep information and personalized recommendations. At first glance, Whoop looks like a simple band since it has no buttons or screens. However, the five LEDs, body temperature sensors and photodiodes allow the Whoop to give you a ton of insight into your sleep.
I also recently tested the new AI Whoop Coach and found it to be intuitive and a great feature if you're already interested in the band. You can ask the AI Coach anything and it will give you personalized answers and insights based on your sleep data. With Whoop, you get sleep data and something to help you interpret it.
Whoop is the ultimate sleep tracker. With its advanced AI-powered technology and comprehensive data analysis, Whoop provides great insights about your sleep quality. This wearable monitors key sleep metrics like sleep stages, heart-rate variability, respiratory rate, hours of sleep and restorative sleep that help you gain a better understanding of your sleep patterns.
Besides the insights, it also has an integrated coach that gives you personalized recommendations, like when to go to bed or mindful breathing techniques, based on your sleep data.
Whoop has a monthly membership option for $30, though after the first month you have to commit to a minimum of 12 months. As such, they have up-front membership options that bring down the cost. The annual membership costs $239 and the 24-month membership is $399.

If you're not into wearables but can't afford to invest in a mattress that tracks your sleep, then you may enjoy the Withings Sleep Tracking Mat. It goes under the mattress, so you don't even know it's there.
It has pneumatic and sound sensors that measure your heart and respiratory rate while you sleep. This sleep tracking mat also measures the movements and sounds you make at night. All of that together allows the mat to record how long you spend in each sleep cycle, which can help you assess your sleep quality.
The mat automatically transfers your data to a sleep diary
Noninvasive way to track sleep
It can turn off lights automatically when you get into bed.
If you sleep with another person, there is a chance it could pick up their movements
You need to have an outlet nearby to charge it

The second-generation Google Nest Hub is an impressive, all-in-one sleep-tracking smart home device. It provides valuable data on your sleep including time spent in different sleep cycles and sleep disturbances, measures heart and respiratory rate, and even changes in light or temperature. The Google Nest Hub can even be used as a sunrise alarm clock to gradually and gently wake you up with light, rather than sounding an alarm.
Aside from its abilities to track sleep and promote better rest, it also has all the bells and whistles you'd expect from a smart home device. You can do everything from play music, ask Google questions with a "hey Google" voice command, control home functions, display personal photos and more.

Our team of sleep experts has been testing and assessing sleep products for years. From mattresses to sleep accessories, we know what it takes to make the cut.
The main criteria considered when looking at sleep trackers are the sleep data points they're measuring. Sleep trackers should offer valuable insights into different aspects of sleep including sleep quality, sleep duration and sleeping patterns. We also took their additional features into account, like their ability to measure blood-oxygen levels, physical activity or other valuable health data.
Another crucial factor when choosing a sleep tracker is its accuracy. There is no device on the market as accurate as a polysomnography test because they don't have the ability to measure brain activity and wave patterns, the true indicators of your sleeping stages and whether you're asleep or awake. However, wearables with heart-rate and blood-oxygen level sensors prove to be the most reliable. For nonwearables, we looked for sleep trackers that measured breathing patterns or external factors such as temperature and light.
From wallet-friendly to premium, there are sleep trackers to fit a range of different budgets. We showcase sleep trackers that offer good results for your money. There are more expensive sleep-tracking fitness wearables and high-tech smart beds you can invest in, but we chose to focus on the ones that offer accurate sleep tracking at a fair price.
What to consider when shopping for a sleep tracker
The sleep tracker market is more than just watches. You've got a lot of variety to choose from, which can get overwhelming if you don't know where to start. Before you start shopping for a sleep tracker, keep these two features in mind.
Before you start shopping, the first thing you should decide is what type of sleep tracker you want to use. Most people think of watches when looking for a sleep tracker, but several other types may be better suited for your needs. There are ring, mattress and mat sleep trackers as well.
Determining what you expect from your sleep tracker will help you narrow down your options. If you want a sleep and health tracker, opt for something like the Oura Ring 3. If you want sleep tracking plus other features like lighting and integrated apps, consider something like the Google Nest Hub. How does sleep tracking work?
How does sleep tracking work?
It depends on your sleep tracker, but they primarily use accelerometers to detect movement, heart rate and oxygen saturation levels. Technology has come a long way and nonwearables use no-contact and low-energy radar that track movement and other environmental factors such as temperature and light to detect possible sleep disturbances.
What do sleep trackers measure?
Sleep phases: Sleep trackers can measure the time you spend in deep sleep, light sleep and REM. Some even sound an alarm at the optimal waking time according to your sleep phases.
Sleep quality: Sleep trackers measure movement and can tell when you're sleeping soundly or tossing and turning.
Amount of sleep: Your sleep tracker can pinpoint your sleep and wake time by tracking your activity (or lack thereof), and by doing so calculate your total time spent asleep.
Sleep disturbances: Some sleep trackers, like those found in mattresses and bedside devices, measure temperature, sound and other external factors that might interfere with sleep quality.

What is the importance of sleep tracking?
While sleep tracking isn't a sure-fire remedy for curing poor sleep, it can offer insights into your sleep stages, possible disturbances that are keeping you awake and lifestyle habits so you're more informed on your own sleeping patterns and what you may be able to change to improve sleep quality. You can also share your results with a doctor who can work with you to improve sleep hygiene and overall quality.
How do sleep trackers work?
Wearable sleep trackers use heart rate, blood oxygen and motion sensors to measure key indicators of your sleeping stages and patterns. Nonwearables rely on motion sensors and low-energy radar to track movement, breathing and environmental changes like temperature and light.
Sleep trackers collect this data to provide valuable insight into sleep duration, sleep quality, how long you spend in certain sleep stages and potential explanations behind sleep disruptions.
