The Oura Ring 5 is official. The new health- and fitness-tracking smart ring is 40 percent smaller than its previous version, the Oura Ring 4, which was released in October 2024. This size upgrade (or downgrade, rather) is arguably the largest update to the smart ring’s hardware.
At 6.09mm wide and 2.28mm thick, the Oura Ring 5 should feel more comfortable around your finger. It also has a new coating for extra scratch resistance, and the smart ring is now waterproof up to 100 meters (328 feet). It features a redesigned sensor to improve skin contact, including more powerful LEDs as well as more precise signal pathways to improve the accuracy of the heart rate readings, particularly at night and during workouts. © Oura The battery has been redesigned to deliver a full week (6 to 9 days, on average) on a single charge. Oura says this will help with continuous wear, which is key to all the software updates that Oura has been investing in (more on that below). The Oura Ring 5 also has a new compact aluminum charging case that has the capacity for five full charges. © Oura Software updates While the hardware updates may seem fairly incremental, Oura is investing in its software, particularly its health tracking. The Oura Ring 5 now has live tracking for workouts. Essentially you can start a workout in the Oura app and see precise second-by-second tracking of your pace and distance if you are running, for example. You’ll still have to pull out your phone mid-run to see these numbers live, which is less ideal for most runners than looking down at their smartwatch to see if they are on pace.
