"Health tracking usually means strapping a bulky smartwatch onto your wrist and then remembering to charge it every few days. The Oura Ring 4 takes a completely different approach by putting comprehensive health monitoring into a sleek ring that disappears on your finger. You forget you're wearing it within minutes which can't be said about even the smallest smartwatches on the market."
"The position of a ring on your finger gives cleaner biometric signals than is possible with wrist-based devices. The arteries in your fingers sit closer to the surface, with less interference from tendons, bones, and movement artifacts. This placement captures heart rate, heart rate variability, and blood oxygen levels with improved accuracy compared to the traditional fitness trackers."
"Sleep tracking represents the Oura Ring's greatest strength: an analysis of your rest in granular detail that actually displays patterns invisible to casual observation. It tracks the stages of sleep, movement, temperature variation, and calculates sleep efficiency scores. When you wake up, you get a detailed picture of how well you actually slept, rather than how many hours you spent in bed."
The Oura Ring 4 places comprehensive health monitoring into a discreet ring that becomes unnoticeable within minutes. Finger placement captures cleaner biometric signals because finger arteries sit closer to the surface, reducing interference from tendons, bones, and movement. Sensors measure heart rate, heart rate variability, and blood oxygen with improved accuracy over wrist-based devices. Advanced sleep tracking records stages, movement, temperature variation, and sleep efficiency scores to reveal patterns beyond simple sleep duration. A daily readiness score combines sleep quality, HRV, temperature, and recent activity to guide training or recovery. Black Friday pricing reduced all colors and sizes to $249.
