The Oura Ring 4 is hands-down our favorite sleep tracker, and it's just had a major price cut thanks to a new Amazon Prime Day deal. The Oura Ring 4, now up to 46% off at Amazon UK provides accurate sleep tracking, a comfy fit, and a panoramic, analytical view of your sleep.

The Oura Ring 4 takes the top spot in our guide to the best sleep trackers, thanks to its advanced features and seamless design. Lead tester Eve Davies rates the Oura Ring 4 for the way it helps her keep a consistent sleep schedule, as the smart ring's accompanying app reminds her when bedtime is approaching. "If sleeping better is your priority, the Oura Ring is the winner," says Davies.

While there are now plenty Amazon UK Prime Day mattress deals, this Oura Ring deal stands out as one of Prime Day's best savings for your sleep. Here's a more in-depth look at the Oura Ring 4, its spectacular Prime Day discount, and why it's great investment for your sleep.

Our lead tester says that the Oura Ring 4 helps her keep to a consistent sleep schedule, making it "my secret to falling asleep fast and waking up refreshed". But what sleep-improving features does the Oura Ring 4 boast?

First of all, the accompanying Oura app sends bedtime reminders to help you maintain your sleep schedule. The next benefit (and arguably most important) is the Oura Ring's accurate, precise sleep tracking, which gives the user key insight into their sleep stages and any nocturnal awakenings, data which betters your understanding of your sleep patterns.

Using your sleep data and sleep scores, the Oura App then offers an AI Oura Sleep Advisor who offers you tips and recommendations to enhance your sleep and improve any problems that may be lowering your sleep score.

Other benefits include a lengthy battery life, sleek screenless design, and an intuitive app that "presents data in a digestible, user-freindly format".
