The Oura Ring Generation 3 has 15 advanced sensors, updated algorithms, and new software features to provide an improved, personalized health experience.
The Gen3 ring comes exclusively in the clean and minimal Heritage design, which has stood the test of time as our most popular style.
The Gen3 ring includes green and red LEDs in addition to infrared (IR) LEDs. This allows measurements of daytime and workout heart rate.
The Gen3 ring includes extra negative temperature coefficient (NTC) sensors and an advanced calibrated sensor to measure differences in your skin temperature.
Finger Detection Sensor
An extra IR sensor in the Gen3 ring helps the algorithm detect and compensate for when your ring is not optimally aligned, allowing for more accurate readings.
Battery & Charger
The new charger features color-coded LEDs for improved charging status displays.
The Oura Ring Gen3 retains the same functions and data insights that made the Gen2 an industry-leading device, including Nap Detection, Social Sharing, and Sleep, Readiness, and Activity Scores. In addition to these features, the Gen3 offers even more improvements and innovations.
Gen3 includes extra NTC sensors for features such as Period Prediction and improved illness detection capabilities.
A blood oxygen measurement (SpO2) feature for viewing nighttime blood oxygen levels.
Advanced sleep staging algorithm, coming in 2022. Read more about Oura's sleep staging study results here.
Predict your period up to 30 days in advance through body temperature measurements.
"Explore Tab"—a constantly updating media library of soundscapes, guided meditations, breathwork, educational content, and more.
With the introduction of the Oura Ring Generation 3, Oura has moved to a monthly subscription membership. Users of Gen3 without a membership will only be able to access Scores for the current day, without insights or additional features. You can learn more about Oura Membership in our Membership FAQs.
Oura will continue to support the Gen2 rings with routine software and firmware updates. All previously available features will be unchanged.
Due to extensive technological differences between Generation 2 and Generation 3 rings, new features will only be released for Gen3.
