The Oura Ring 5 and the Apple Watch Series 12 are two of the most talked-about health wearables on the market, and Engadget has pitted them head-to-head. Both devices collect much of the same data — sleep, steps, estimated calorie burn, heart rate and heart rate variability — and both offer a Readiness score that tells you whether to push hard or take it easy. The Oura Ring 5 starts around $400 (roughly 1,160 TND), while the Apple Watch Series 12 sits in the same price territory.
The choice between them is less about which sensor is better and more about how you live. The Apple Watch Series 12 needs an iPhone 11 or newer running iOS 27, so Android owners are effectively locked out, whereas the Oura Ring 5 syncs with both Apple Health and Android's Health Connect. Battery life, subscriptions and how seriously you train then decide the rest.
Apple Watch Series 12 specs and features
The Series 12 is a full smartwatch, not just a tracker. It comes in 42mm and 46mm sizes, with the larger model costing $50 extra, and packs 64GB of storage plus Apple's S11 processor. A touchscreen, Apple Pay, notifications and offline trail navigation mean it can handle plenty of tasks without pulling out your iPhone.
Cellular models, starting at $500 (about 1,450 TND), can go online without Wi-Fi — something the Oura Ring 5 cannot do at all. Apple also gives its health insights away at no extra cost, because its real goal is keeping you inside its ecosystem. According to 9to5Mac, Series 12 and Ultra 4 owners can add live heart rate, step count and readiness complications straight to the watch face.
