Best sleep trackers 2026: From Garmin to Oura

If you’re struggling with your sleep and you can’t work out why, a sleep tracker might help. On its own, it won’t solve your problems, but it can show patterns and provide useful information for doctors as part of a diagnosis.

Basic sleep trackers collect data like sleep duration and time spent in each stage (light, deep and REM). More advanced models may track heart rate, stress levels and body temperature. Often, these stats are combined to calculate a sleep score and accompanying apps may suggest adjustments to your routine.

We’ve reviewed dozens of fitness trackers and accessories for their sleep tracking capabilities, but only eight made the cut here. Prices range from £100 for Amazon own-brands to over £2,500 for an Eight Sleep pod system. Remember to factor in running costs and rolling subscription fees.

The best sleep trackers of 2026: At a glance

How we test sleep trackers

Our experts test the trackers for at least two weeks. Some are purely for sleep, while others incorporate the technology as part of their broader offering. We score each tracker against the following criteria:

• Design and build: The tracker should look good and feel well-made. If it is wearable, we consider whether it feels comfortable over several hours of use and whether it’s sufficiently discreet to wear during the day.
• User experience: We navigate the app interface to make sure it offers insightful, personalised recommendations in a user-friendly fashion.
• Accuracy: Where possible, we try using multiple sleep trackers at the same time (or back to back) to see whether the results are consistent.
• Results: We consider whether the results align with how we perceive our own sleep quality. We award bonus points for trackers that help you to get better sleep as well as monitoring your current sleep.
• Value for money: We compare the upfront cost to similar models, factoring in any running costs or subscription fees.

How to choose the best sleep tracker

“Trackers generally fall into three categories: rings, smart watches, and bedside or under-mattress sensors,” says Kerry Davies, certified cognitive behavioural therapist for insomnia and founder of The Sleep Fixer. “Rings tend to be less obtrusive, so they’re popular with people who don’t like wearing a watch at night.”

A big consideration is the data that you would like to see. “For some people, a simple overview of sleep duration and consistency is enough,” Davies says, “while others enjoy exploring trends over time. Smart watches like Apple Watch or Fitbit offer broader health tracking but can feel bulky for some sleepers.”

“Price-wise, a sensible range is usually £100 to £300, depending on features,” Davies continues. “Some of the more premium devices also charge a monthly subscription.”

“Ultimately, the best sleep tracker is one that feels comfortable, doesn’t disrupt sleep and is used as a guide rather than a judgement tool. The data should support better sleep habits and not create pressure or perfectionism.”
