Hardware
The Oura Ring Generation 3 comes in the Heritage and Horizon models. For best fit and most accurate sensor readings, make sure your ring is aligned so that the sensor bumps are against the palm-side of your finger.
Gen3 hardware includes:
- Green and red LEDs, in addition to infrared (IR) LEDs. This allows measurements of daytime and workout heart rates
- Extra negative temperature coefficient (NTC) sensors to measure differences in your skin temperature. This enables period prediction and improved illness detection
- An extra IR sensor, which helps the algorithm detect and compensate for when your ring is not optimally aligned, allowing for more accurate readings
- Accelerometers, to detect your daily activity, steps, and common workout types
- The Gen3 charger features color-coded LEDs for improved charging status displays
Technical specs for the Gen3 ring can be found in our Product Safety & Use article.
Software
The Oura Ring Generation 3 retains the same software features of Gen2, including nighttime resting heart rate, heart rate variability, skin temperature, and respiratory rate. Additionally, Gen3 includes:
- Daytime heart rate, live heart rate, and workout heart rate measurements
- Period prediction and other reproductive health features
- Blood oxygen sensing (SpO2)
- A new sleep staging algorithm for improved sleep measurement
- Location information for workouts using automatic activity detection
Body clock and chronotype, Explore tab, and personalized activity goals are available for Gen2 and Gen3 rings.
