If you struggle to get enough shuteye, tracking could help you better understand your sleeping patterns and help improve the quality of your sleep.
Sleep trackers come in all shapes and sizes, from wearables to devices on your bedside table to the bed itself. With years of testing mattresses and sleep products under our belts, we’ve used our experience to assess the best sleep trackers available.
What is the best sleep tracker?
The best sleep tracker is the Whoop 4.0 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 band’s five LEDs, body temperature sensors and photodiodes provide a ton of insight into your sleep.
I also recently tested the new AI Whoop Coach and found it 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 help with interpreting everything.

The second-generation Google Nest Hub is an impressive, all-in-one sleep-tracking smart home device. The Sleep Sensing feature requires an additional subscription and will provide sleep data, 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 be used as a sunrise alarm clock to gradually and gently wake you up with light rather than sounding an alarm.
Aside from its ability to track sleep and promote better rest, it has all the bells and whistles you’d expect from a smart home device. You can play music, ask Google questions with a “hey Google” voice command, control home functions, display personal photos and more.

How we chose the best sleep trackers
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.
Features
The main criteria considered when looking at sleep trackers are the sleep data points they measure. Sleep trackers should offer valuable insights into different aspects of sleep, including sleep quality, duration and patterns. We also considered their additional features, like the ability to measure blood-oxygen levels, physical activity or other valuable health data.
Accuracy
Another crucial factor when choosing a sleep tracker is its accuracy. No current device on the market is as accurate as a polysomnography test, which measures brain activity and wave patterns — 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 non-wearables, we looked for sleep trackers that measured breathing patterns or external factors such as temperature and light.
Price
From wallet-friendly to premium, there are sleep trackers to fit a range of different budgets. We showcase sleep trackers that offer solid 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 fairer price.
What to consider when shopping for a sleep tracker
The sleep tracker market is made up of more than just watches. You have a lot of variety to choose from, which can be overwhelming if you aren’t sure where to start. Before you begin shopping for a sleep tracker, keep these features in mind.
Type
Before you start shopping, you should first decide what type of sleep tracker you want to use. Most people think of watches when looking for a sleep tracker, but other types may better suit your needs. There are rings, mattresses and mat sleep trackers as well.
Price
The price range for sleep tracker devices varies, so determining your budget will help narrow down your best options. It’s also important to factor in the monthly or yearly subscriptions that some sleep tracker devices require.
Additional features
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 or Fitbit. If you wish to track sleep and would also enjoy features like lighting and integrated apps, consider the Google Nest Hub.
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 non-wearables use no-contact and low-energy radars to 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.
- Time spent in deep sleep and REM
- Sleep duration
- Heart rate
- Blood-oxygen levels
- Breathing patterns
- Temperature and light disturbances (if applicable)
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.
Wearable sleep trackers use heart rate, blood oxygen and motion sensors to measure key indicators of your sleeping stages and patterns. Non-wearables 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.
