With one of the best sleep trackers, you can gain valuable insight into your sleep patterns, and the amount – and quality – of sleep you're getting. While a sleep tracker can't force you to go to bed at a sensible time (not yet, anyway), it can show you how catching some quality zeds can improve your energy levels the next day. There's some crossover between sleep trackers and the best fitness trackers (opens in new tab), but this guide is all about finding devices that specialise in monitoring your night time routine.
If you're in a rush to find the best sleep tracker, we'd currently recommend the Fitbit Inspire HR. It features heart rate tracking so you can monitor your different sleep stages, and also works as a fitness tracker for the waking hours. While its accuracy isn't 100%, it's still a great all-rounder suitable for most people (here's exactly how Fitbit tracks sleep (opens in new tab), if you're interested).
However, if you want all the sleep data, you should look at a dedicated tracker like the Withings Sleep Analyzer, which sits under your mattress and keeps tabs on everything that happens in the night. Alternatively the Kokoon Sleep Headphones (currently top of our best sleep headphones (opens in new tab) roundup) will help you monitor your sleep as well has helping you sleep better.
If you're here because you're struggling to sleep, you might also want to explore our ranking of the best mattresses (opens in new tab), or pick up one of the best weighted blankets (opens in new tab), which work wonders for some restless sleepers.

How to choose the best sleep tracker for you
There's no shortage of different sleep trackers out there. Catering for mostly every budget as well as lifestyle, it's important to know exactly what you want it to do for you before you make a purchase. Here's a brief overview of what to consider.
Know your budget. It's a common thing to consider with any technological purchase but it's important that you think about how much you want to spend. Sleep trackers can cost as little as £25-30 but they can also cost hundreds of pounds. Don't feel obliged to spend a lot unless you really need all the features.
Consider the features you want. Many sleep trackers do far more than just track your sleep. They also tend to track things like your steps each day, or even double up as smartwatches. It's important to know if you need these features or not as generally the more features, the more expensive the purchase.
How comfortable the tracker is. Do you want to wear a wristband all night? How about a full-on smartwatch? Either is perfectly possible but if you're a light sleeper, you may feel uncomfortable doing so which will then affect your ability to sleep. An under the mattress solution may be a better option here.
The best sleep tracker 2022
The Fitbit Charge 5 is a high-end fitness tracker with a stunning looking AMOLED display, it's far classier than other Fitbits as well as more roust thanks the protection provided by the Corning Gorilla Glass 3 screen. In our Fitbit Charge 5 review, our tested noted that it's a little on the small side, but that makes it a comfortable fit when you're snoozing: you won't have to worry about it getting in the way. A subtle always-on screen can be tweaked on or off, proving useful at night.
As you might expect, this Fitbit does much more than just track sleep. With its extensive array of sensors, it can measure stress on your wrist, offer an ECG, along with a daily readiness score to give you insight into how you're doing today. Heart rate monitoring isn't perfect and as with other Fitbits, the Fitbit Charge 5 can get confused if you simply stay still. But for the core focus of this guide at least, the Fitbit ecosystem is well designed for detailed sleep analysis, right down to its monthly sleep profile tool. As one of the best Fitbits on the market, it's on the pricey side – you'll find more budget-friendly options further down our ranking.
If you want a smartwatch that also tracks your sleep comprehensively, the Withings Steel HR Sport is a fantastic if somewhat cumbersome option. It's a full-sized watch so it won't be the comfiest of things to wear if you lean on your wrist at night, but it tracks very accurately. That's thanks to automatic sleep monitoring that looks at your light and deep sleep cycles, detects any interruptions, and how regular they become. Each morning, you can enjoy some deep insight into how you're doing each night.
As well as that, the Withings Steel HR Sport is a powerful smartwatch for the active user. It tracks many different sports, has fantastic battery life, and estimates your ability level each step of the way. For those simply wanting to track their sleep, it's overkill, but if you want an all-in-one solution, it's great.
A little long in the tooth, the Fitbit Inspire 2 remains a reliable option if you want a budget-priced Fitbit that offers sleep and fitness tracking. It's a little basic, lacking GPS and Fitbit Pay but as we explore in our Fitbit Inspire 2 review, for sleep tracking, you can't go wrong. It's sufficiently lightweight and comfortable enough that you won't notice wearing it at night. By doing so, you receive extensive stats via the Fitbit app each morning. This includes a score out of 100 to show how well you slept, the length of time you were asleep, along with a breakdown of when you achieved REM sleep and when you were sleeping lightly. Upgrade to Fitbit Premium and you can view your sleeping heart rate too, which can be very useful. See how this compares to another budget fitness tracker in our Samsung Galaxy Fit2 vs Fitbit Inspire 2 face-off.
Kokoon makes what we think are the two best sleep headphones around, and both come with sleep tracking features built in. We think the in-ears are the better sleep tracker option because they're comfier to sleep in than the over-ears, which do appear further down our ranking (more on how the two compare in our Kokoon Nightbuds vs Kokoon Relax sleep headphones face-off).
While it isn't a fitness tracker so it won't help out during the daytime hours, these are a good option for helping you sleep better, as well as tracking how well that sleep is going. When tied into the MyKokoon app, it's possible to look up guided relaxation exercises, natural soundscapes, or listen to a podcast that is designed to soothe your mind. In our Kokoon Nightbuds review, our tester noted that it can take a bit of practice to master fitting them securely for the night, but once they're in, they're quite comfortable even if you toss and turn in the night.
The Nightbuds use an infrared light system to monitor your skin at night, tracking your heart rate and whether you're asleep. From there, it determines how long it took you to fall asleep, and how long you slept for. It uses that information to lower the volume of the recording you're listening to. Sound quality could be better and you need to take some time to get used to them, but the Kokoon Nightbuds are a clever alternative to wearing something on your wrist, and they're a great way of incorporating relaxation techniques into your routine.
If the idea of wearing a wrist strap all night is unappealing then the Withings Sleep Analyzer is the solution for you. You slip it under your mattress, plug it in, and leave it to do all the hard work for you, allowing you to sleep encumbered. Thanks to that, it offers far more advanced sleep tracking than its competitors with an in-depth analysis of your sleep cycles, durations, and any interruptions.
It's also able to detect any snoring episodes as well as spot any signs for sleep apnea, an underdiagnosed condition that can be a huge problem if left untreated. In terms of sheer sleep tracking power, you can't go wrong with the Withings Sleep Analyzer but it is purely a sleep tracker. That means it's a bit of an expensive purchase to track one issue through your day, but we appreciate that its app ties into others well, giving you insight into your general health and body performance all day long.
There's also very little else out there that's quite as accurate as the Withings Sleep Analyzer and the fact it's so unobtrusive yet effective is very appealing. Head to our Withings Sleep Analyzer review to find out more.
Another excellent budget sleep tracker is the Amazfit Bip 3 Pro. This cheap tracker's companion app contains plenty of insight for you to explore. It gives you a sleep score (plus emoji representation), a simple bar graph to highlight deep sleep cycles, and tells you your average heart rate for the night, too. You can see how well you're sleeping compared to other users, and it'll even encourages you to track what you're doing before you went to bed, so you can see if, for example, eating late in the day or playing a game before bed impacts your sleep. You can't use this to monitor for sleep apnea or snoring, but other than that, its sleep features are pretty comprehensive. In our Amazfit Bip 3 Pro review, our tester actually found this device tracked sleep more accurately than the Fitbit Inspire 2. So why is that sitting above the Amazfit in our list? Because the latter is just not massively comfortable to sleep in. If you're not particularly sensitive to sticky straps, though, this could be a great choice for you.
If the Charge 5 (at number 1) is out of your price range, the model down is still a great pick. You're still getting a very comprehensive sleep tracking package: this tracker will offer an overall 'sleep score', which attempts to rate your slumber each night, and – provided you've subscribed to Fitbit Premium – you can also dig into a detailed breakdown of how long you spent in each sleep stage (light, deep, REM etc.). There's also a blood oxygen tracking feature that could be helpful in alerting you to health issues such as sleep apnoea. Because it's a Fitbit, you also get a bunch of other features, including GPS for tracking runs, rides and hikes.
The bulkier sibling of the Kokoon Nightbuds higher up this list, the Kokoon Relax Sleep Headphones are a similar combo of headphones and sleep tracker (they were originally just called the Kokoon Sleep headphones, presumably before the brand realised they might want to make more than one option). While they're no good for side sleepers, according to the tester in our Kokoon Relax sleep headphones review, if you lie on your back, they're ultra comfy.
Active Noise Cancellation keeps background noise at bay, and there are plenty of clever sleep tracking tools to explore, too. Each earcup features EEG brainwave sensors built in so once they come into contact with your ears, the headphones can figure out when you've fallen asleep, how long it took, and how deeply you're sleeping. It learns as it goes along, recommending programs and audio from the dedicated app that – in theory – will help you rest and sleep better. Basically, it's like a sleep therapist, allowing you to find the music and white noise that works best for you before tracking how you're doing so you know exactly what works for you.
On a tight budget? The Xiaomi Mi Band 4 (opens in new tab) might not have the 'wow' factor but it does exactly what you need of it, and it costs significantly less than other sleep trackers here. That instantly makes it appealing if you're not sure if you'll commit to wearing a sleep tracker every night. Like the others, it works as a general fitness tracker too so you can easily monitor your daily steps, calories burned, as well as your heart rate. It's swim-proof too proving ideal for avid swimmers.
In terms of sleep tracking, it uses its heart rate monitor alongside detecting your restful moments, before formulating a chart that picks up on sleep time, sleep depth and how many times you wake up. Like the device itself, the app isn't as stylish as the Fitbit but it's a lot cheaper. Just bear in mind that it's a little chunky for the night time.
If you've been considering investing in one of the best Garmin watches, but you also want to track your sleep, the Garmin Forerunner 55 is a good introduction to both. Considered the ideal first running watch, it's more affordable than other Garmins while offering plenty of options and workout tracking. Besides personalised run workout suggestions and all kinds of things for the daytime, it also allows you to track sleep duration, while recording sleep stages including REM sleep, and it monitors respiration rate too.
At times, it's not as accurate as something like the Withings Sleep Analyzer, but if you want something that's an all-rounder, the Garmin Forerunner 55 means you can monitor your activity levels 24/7 without feeling like you need to own a dedicated solution. Head to our Garmin Forerunner 55 review to find out more.
