T3 reported the Amazon UK Prime-exclusive offer on 5 October 2026, listing £199 against a £349 RRP: a £150 saving, or 43%. T3 called it the lowest UK price its writer had seen; that is a dated price-history judgment, not a guarantee that the offer remains live.
What the £199 Oura Ring 4 deal includes
T3’s 5 October 2026 report said the Amazon UK offer was exclusive to Prime members and varied by finish and size. Silver and selected Black and Stealth sizes were listed at £199 at the time of that report. Check the live listing for your preferred combination and eligibility before ordering: the reported discount does not establish that every size or colour is available at that price.

T3 compared £199 with a stated £349 RRP and described earlier large sales as reaching around £199.99. Its claim that £199 was a UK record low belongs to that report, rather than establishing a permanent lowest price. Read T3’s dated deal report.
Who should consider the Ring 4?
The Ring 4 suits someone who wants sleep and recovery tracking in a small, screen-free form rather than a watch-style display. Oura lists continuous heart-rate tracking, sleep heart-rate variability and respiration rate, sleep blood-oxygen sensing, temperature variation, movement and activity tracking among its capabilities. The company describes its Smart Sensing platform as adapting to the wearer’s finger and activity; that is the manufacturer’s description, not independent proof of clinical accuracy.

Oura says the ring has a fully titanium design with recessed interior sensors. Its listed specifications include a 7.9 mm width, approximately 2.88 mm thickness, weight of 3.3–5.2 g depending on size, and 100 m water resistance. It supports iOS and Android, Bluetooth Low Energy, airplane mode, and integration with more than 40 apps. These are manufacturer specifications and compatibility claims. See Oura’s Ring 4 specifications and features.
Include the membership in your real cost
Oura’s UK product page lists Membership at £5.99 per month or £69.99 per year after tax, with the first month free for new members. Oura lists detailed sleep analysis, heart-rate tracking, temperature, blood-oxygen sensing, stress, activity, heart-health and women’s-health features as available with active membership. So the £199 offer is the hardware price, not the full cost of ongoing access to the membership features. Check Oura’s page for current prices and terms. Oura Ring 4 product page.

Battery life depends on how you use it
Oura estimates 5–8 days from a full charge. That range comes from Oura Member Care testing new, unworn rings in sizes 8–10, with eight hours of sleep tracking, one hour of daily activity detection with heart-rate capture, and blood-oxygen sensing switched off. Oura says enabling blood-oxygen sensing may reduce battery life by up to two days; ring size, activity, settings, device age and usage also affect runtime. Treat the estimate as a range under specified conditions, not a promise for every wearer. Oura lists a typical charging time of 20–80 minutes, depending on the starting charge.

Ring 4 comes in sizes 4–15, and Oura says sizing differs slightly between generations. Use the dedicated Ring 4 sizing kit rather than assuming an older Oura sizing kit will fit identically. Oura also recommends positioning the sensors against the palm side of the finger for the best fit and readings. Because the reported deal price and stock varied by size, confirm both fit and live price before placing an order.
