Oura Ring 4: Smaller, longer battery life, and superior intelligence.
Oura Ring 4 continues to assert its leading position in the smart ring segment with a more comfortable design, 5-6 day battery life, and intuitive health analysis application.
Sophisticated design: Superior comfort and durability.
One of the biggest changes on the Oura Ring 4 is the internal design. Gone are the two protruding sensor bumps of the previous generation; the inside of the ring is now completely flat, giving it the feel of a regular ring. This change eliminates the feeling of discomfort or the need for time to get used to it.
The band also appears slightly thinner, contributing to overall comfort. With a design lacking the large plateau found in some older versions, the Oura Ring 4 looks more like a piece of jewelry than a technological device. The metal finish, such as the Rose Gold version, also demonstrates remarkable durability, resisting scratches far better than expected after months of use.
Miniature sensor systems: The power hidden within.
Despite its compact size, the Oura Ring 4 is equipped with a full suite of advanced sensors to monitor health metrics. The device uses a system of green, red, and infrared LEDs to continuously measure vital indicators just below the skin's surface.
- Blue and infrared LEDs:Measure heart rate and heart rate variability (HRV).
- Red and infrared LEDs:Measure blood oxygen saturation (SpO2).
- Temperature sensor:Recording changes in body temperature is useful for tracking menstrual cycles or detecting early signs of illness.
- Accelerometer:Track movement and physical activity throughout the day.
All this data is collected continuously, especially while sleeping, to provide a comprehensive picture of the user's health.
App experience: Where health data becomes easy to understand.
The real highlight of the Oura Ring 4 lies in its accompanying application. Oura has successfully compiled a large amount of complex data and presented it in an extremely intuitive and easy-to-understand way. This is the biggest differentiating factor compared to its competitors.
The app's main interface displays core metrics developed by Oura's algorithm, including Readiness, Sleep, and Activity. Users can quickly grasp their overall health status or tap on each metric to view a detailed analysis. Oura also continuously updates the app to provide more useful features, creating an excellent user experience, despite the $6 monthly subscription fee.
Real-world performance and battery life: Your companion all week long.
In terms of accuracy, the data collected by Oura Ring 4 is comparable to other smart wearable devices. While its workout tracking capabilities may not be as detailed as dedicated sports watches, it still provides sufficient information for the average user. Oura's philosophy is to focus on the overall health picture rather than just individual workouts.
Battery life is a notable improvement. The Oura Ring 4 can last 5 to 6 days on a single full charge, up from about 4 days of the previous generation. Charging time is also very fast, taking less than an hour to fully charge from 0%. The new charger is also designed to be more compact and stable on a desk.
Is Oura Ring 4 the right choice for you?
At a starting price of $349, the Oura Ring 4 is a worthwhile investment. This price reflects the research and development costs involved in integrating advanced technology into a compact device. It's particularly suitable for users who prioritize minimalism, don't want a constantly displaying notification screen on their wrist, but still want comprehensive and detailed health monitoring.
If you value a discreet, comfortable wearable with long battery life and insightful health data delivered through an excellent app, the Oura Ring 4 is virtually unrivaled. It has successfully built upon the achievements of its predecessor, continuing to set the standard for the smart ring category.
