At first glance, the Oura Ring 4 may look similar to its 3rd generation counterpart, but there are some exciting upgrades. First of all, this new version is made entirely of titanium, giving it an elegant and modern look. Additionally, the flat edges are gone; Each ring is now perfectly round, just like the current Horizon models. One of the most notable changes is the design of the sensors. Instead of the old dome-shaped covers, the sensors are now seamlessly integrated, offering a flatter profile that should feel more comfortable on your finger.

Ōura is also introducing a wider range of sizes, increasing from eight to twelve options. There's also a new color range, including a revised black option with a more durable coating to address previous customer complaints. The Oura Ring 4 is available in six stylish versions:

  • Gold
  • Rose gold
  • Brushed silver
  • Stealth
  • Black
  • Silver

Oura Ring 4 Smart Sensing or probably the biggest update

The standout upgrade comes from the software side, introducing the new Smart Sensing platform. Ōura claims that its innovative algorithm addresses a common problem with smart rings: the different sizes and shapes of people's fingers. As we move throughout the day, rings can shift from their ideal position, resulting in inaccurate data collection.

To combat this, the updated algorithm increases the number of signal paths from eight to 18, allowing the ring to determine the best signal at all times. So in practice, you don't have to worry about the ring always fitting perfectly on your finger to get continuous, accurate data.

In addition to improved accuracy, Ōura says the new algorithm increases battery life up to eight days, depending on ring size. Of course, these numbers come from controlled studies and test environments, so it will be interesting to see how they perform in everyday use.

Oura Ring 4 and its improved app

Ōura is rolling out a new app design for all members in the coming weeks. The revamped app will include three main sections:

  • Today: This tab provides a dynamic snapshot of your biometric data, tailored to the time of day and your personal health goals.
  • Vital signs: The Vital Signs section allows users to explore their metrics and results in more detail.
  • My health: The My Health tab focuses on long-term trends in your health data.

Along with the fresh new look, Ōura introduces an updated daily stress metric to help you better understand your stress levels throughout the day. In addition, tracking your workouts becomes easier thanks to automatic activity detection for 40 different types of activities. And for those focused on reproductive health, Ōura now offers predictions for your fertile window if you're trying to conceive. Finally, Oura Labs, the section of the app where you can explore and provide feedback on experimental features, is also expanding to Android users after already being available on iPhone. Android users can now also interact with Oura Advisor, the brand's generative AI chatbot.
