You may think the last thing you need to get comfortable and rested on a night is a piece of tech strapped to your arm or to your bed. But the best sleep trackers are designed to help you keep tabs on how long you sleep and the quality of your rest so you can begin to make changes to your routine for the better.
UPDATED: While the best sleep tracker may well be a dedicated device, the Apple Watch is set to add sleep tracking in Watch OS7. Set for release 'in the Autumn', the software update finally brings the most sought-after feature for Apple Watch since its release in 2015.
Why? Because it’s official: we’re not getting enough sleep. And, according to the sleep experts, this lack of quality rest can have a negative impact on our moods, stress and long-term health.
There are lots of things you can try to improve your sleep, from buying one of the best mattresses to trying CBT to deal with stress, but getting a better understanding of your sleep patterns and your sleep behaviour can be an important first step.
There are lots of fitness trackers and smartwatches with sleep tracking already built-in. But not all sleep tracking tech is created equal. We’ve collected together our favourite devices with sleep tracking smart features, as well as gadgets built solely for sleep, which you don’t wear but strap to your bed or place on your bedside table.
If there’s a device or wearable gadget that helps you track your sleep, and sleep more soundly as a result, then upvote your favourite or let us know in the Shortlist entry box below.
- We recommend two Fitbits in our best sleep trackers list below, but more of the Fitbit range can track your sleep. Check out our guide to the best Fitbit.
Best sleep tracker
Like the Inspire HR, which also makes our list, it uses your movement data and heart rate to tell you how long you sleep and which stages of sleep you were in throughout the night.
The Fitbit Versa may not be the cheapest tracker around, but there’s now a Lite version available for £129.15 from Amazon, which is just as good at tracking your sleep. If you want the latest and greatest tech, check out the Fitbit Versa 2, the upgraded wearable with Amazon’s voice assistant Alexa now built-in, which is available for £199 from John Lewis.
Be warned: there’s a lot of data to wade through on the app (or via the web) each morning, which is why it’s no surprise this is a sleep tracker aimed at athletes or those who are very serious about their training and performance each day.
