The Oura Ring 4 Is $100 off for Black Friday

"This generation of the Oura smart ring has a number of major improvements, but the biggest upgrade is to the overall wearability. The sensors have been recessed further into the body of the ring itself, which reduces the overall thickness considerably and allows for a wider available range of ring sizes. They also cover a wider portion of the ring, so there's no need to keep it oriented in one specific direction to get proper readings."

"The battery life has improved a lot as well. The older Oura 3 could run for around three days before it needed a charge, Our reviewer, Adrienne So, reported that the Ring 4 tracked a full weekend of hiking and physical activity, as well as a music festival, and still had enough juice for at least a couple more days."

"You get a ton of health and physical fitness data from the ring, which is neatly sorted into daily physical data, detailed vitals, and longer trends over time, all organized in the app on your phone. If you want to also keep track of your food intake, a new Meals feature lets you take photos of what you eat and then track its effects on your body."

Oura Ring 4 improves wearability by recessing sensors into the ring body, reducing thickness and expanding available sizes while widening sensor coverage to remove orientation needs. Battery life now lasts multiple days, able to sustain extended activity and still retain additional charge. The companion app organizes daily physical data, detailed vitals, and long-term trends for clear insight into health and fitness. A Meals feature enables photo-based food tracking to observe physiological effects. Integration with Natural Cycles supports period prediction using basal body temperature. Select finishes are discounted to $249, with other options priced higher.
