Smart rings have evolved from novelty gadgets into must-have tech for health-conscious users in recent years, and Oura is leading the pack with the Oura ring 4.
“It has the best sleep tracking of any wearable, with a lot of science to back it up. There are new features rolling out all the time, and it’s the best activity tracker I’ve found in a smart ring so far,” says senior tech critic Alex Lee. All of this comes in a sleek, unobtrusive design that sits on your finger, leaving your wrist free for a watch or other accessories.
This compact, tech-packed design will cost you, however. The Oura ring 4 currently retails for £349, with an extra £5.99 monthly subscription fee needed to unlock all of its features. That’s why, if you decide this is the wearable for you, it can be worth waiting to snap one up in the Black Friday sales.
Oura is yet to reveal whether its products will be discounted during this year’s mega-sales event, but the brand has a notoriously fleeting relationship with price cuts. However, we’ll be keeping our ear to the ground and updating this page as soon as we hear of any offers.
In the meantime, Amazon has dished up a modest discount on the Oura ring 4 ahead of Black Friday. Keep scrolling for more details about the deal and how the device compares with the Oura ring 3.

Discounts on Oura rings are rare, so this modest £30 saving at Amazon is still worth considering. It may not be the biggest of reductions, but it will pay for five months of Oura membership and grant you unfettered access to the many features on offer from the sleek wearable.
“The main benefit that the Oura ring 4 provides, compared with the gen 3, is improved durability, comfort and accuracy,” says senior tech writer Alex. “This isn’t a generational upgrade over the Oura ring 3, merely strengthening its position as the best smart ring out there for sleep tracking and recovery.”
If you miss out on this Amazon deal, you can currently find the Oura ring 4 reduced to the same price at John Lewis. However, at both retailers, the discount is limited to certain ring sizes, so be sure to check yours before you order.

The Oura ring 3 does not have the same smart sensing platform as the latest generation, while also weighing slightly more and having seven days of battery life rather than eight. But there is still a lot to like, and it’s far more affordable than its successor.
“If you’re looking for a sleep tracker or activity tracker or just want to know as much as you can about your body, the gen 3 Oura ring will tick a lot of boxes, in one tiny package,” our reviewers noted in their review.
“For those keen to enter the world of biohacking and take steps to optimise your sleep and energy and track your readiness for exercise and your cycle more effectively, the Oura presents one of the easiest ways to do all this. It’s also a great option for anyone who doesn’t love wearing a tracker on their wrist and prefers a smaller wearable that takes up less real estate on the body.”
When is Black Friday 2025?
Black Friday falls on the day after Thanksgiving in the US. For readers on this side of the pond, that means it will land on 28 November this year.
Most brands will introduce their discounts over the course of a fortnight before the event, and continue to offer savings in the weeks that follow. However, most of the best deals can usually be found over the Black Friday weekend, which starts on Friday 28 November and ends on 1 December (aka Cyber Monday).
