A titanium smart ring that tracks sleep, heart rate, stress, and over 20 biometric indicators without a screen, a strap, or anything that announces itself on your wrist is a different proposition to most wearables, and at £139.99 it is close to the cheapest it has ever been.
The Oura Ring Gen3 Horizon has dropped from £237.70 to £139.99, just £10 above the £129 Black Friday price, making this one of the better windows to buy outside of the November sale period.

Oura’s Gen 3 Horizon Smart Ring is close to its Black Friday bargain
If you missed it last November, the Oura Gen3 Horizon Smart Ring is once again hovering near its Black Friday bargain.

The research-grade sensors inside the 4-star Oura Ring Gen 3 Horizon monitor over 20 biometric indicators including sleep stages, heart rate, heart rate variability, stress, and activity, and because the ring sits on your finger rather than your wrist, the pulse readings are more accurate than most wrist-based wearables can manage.
Battery life runs to up to seven days on a single charge, which means weekly charging rather than the daily or every-other-day routine that most smartwatches require, and the titanium construction keeps it lighter than the average wedding ring while remaining non-allergenic and water resistant.
The ring integrates with over 40 apps including Apple Health, Google Health Connect, Strava, Natural Cycles, and Flo, so the data it collects feeds into whatever health ecosystem you are already using rather than sitting in isolation.

An Oura Membership is required to access the full range of insights and personalised health data, with the first month free and a subscription of £5.99 per month after that, which is worth factoring into the overall cost before buying.
The Oura Ring Gen 3 Horizon is available in sizes 6 through to 13, and because Oura sizing does not correspond to standard ring sizes, the brand recommends purchasing a sizing kit on Amazon before committing to a size, with a £10 Amazon credit included to offset the cost against your ring purchase.
Outside of Black Friday itself, £139.99 for the Oura Ring Gen3 Horizon in Brushed Titanium is about as close to the November low as this ring is likely to get until the sales come around again.
