Oura Ring 4 discounted up to 48% for Prime Day

The Oura Ring 4, a health‑tracking wearable that measures more than 50 metrics such as sleep, activity, heart and women’s health, is being offered at a steep Prime Day discount. Prices have been cut by as much as 48%, dropping the regular $399 price to around $226 for most finishes. The sale also includes a free first month of the Oura membership, after which the subscription costs $5.99 per month. The ring provides up to eight days of battery life, an adjustable size range from size 4 to 15, and a dedicated sizing kit. It is eligible for HSA and FSA reimbursement. Reviewers note that the newer Oura Ring 5, while slimmer and with slightly longer battery life, does not offer sizes smaller than 6, making the Ring 4 the more inclusive option for users with smaller fingers.
