The Oura Ring 4 stands out as a smart ring alternative to traditional smartwatches, offering enhancements in software and performance. It accurately tracks heart rate and blood oxygen levels, along with automatic activity detection. With no subscription for basic functions, advanced insights require a $5.99/month fee. Improved design includes a slimmer shape and durable titanium material, with battery life lasting seven to eight days. Ideal for casual athletes, it discreetly monitors key health metrics while lacking advanced smartwatch features like notifications and smart alarms.
The fourth-generation Oura Ring brings a handful of meaningful software upgrades over its predecessor, featuring an accurate algorithm for tracking heart rate and blood oxygen levels.
Battery life has also improved significantly, lasting up to seven or eight days on a single charge, compared to three to four days in previous models.
