Evie Ring vs Oura Ring: Which should you buy?

It’s hard to believe that a simple pedometer was once the pinnacle of fitness trackers. The introduction of Bluetooth headsets, iPods, and the Fitbit in the early 2000s created an explosion of wearable tech with a lasting momentum that we’re still seeing to this day.

In the constantly evolving world of wearable technology, smart rings have emerged as a sleeker alternative to casual, bulky fitness trackers. Among the frontrunners are the Oura Ring—one of the first and most-known smart rings—and the Evie Ring, a new model designed specifically with women and people assigned female at birth’s health in mind.

Evie Ring vs Oura Ring

Both rings boast claims of superior fitness and biometric tracking, offering insights into sleep, stress, and your menstrual cycle. We’re comparing the Evie Ring and Oura Ring based on price, features, battery life, and more, to see which smart ring delivers a superior experience.

Price

Buying any device means participating in the balancing act of getting the most bang for your buck while also ensuring you get the look and features that matter to you. For wearable tech, especially, this means paying special attention to the finish. The Evie Ring comes in silver, gold, and rose gold and costs $269 regardless of the finish or size. There is also no subscription required to access the features of the Evie Ring.

Oura's latest edition, Oura Ring 4, comes in the smooth-designed Horizon style and starts at $349 for silver and black colors, ranging up to $499 for gold and rose gold. It's also made entirely of titanium. The Oura app subscription is also required to access more detailed information and costs $5.99 per month or $69.99 annually.

The older 3rd generation Oura Ring has a titanium exterior with an epoxy interior. Like the 4, it also comes in the Horizon style, or you can choose the plateaued Heritage style. Consumers can no longer get either style in rose gold or gold, but it is available in four other colors: silver and black (now discounted to $199.99 from $299) and Stealth and brushed titanium (now discounted to $229 from $349).

Winner: Oura Ring Gen 3

Metrics

While the Evie focuses more on metrics surrounding the menstrual cycle and mood, the Oura Ring stands out with a more complete wellness spread and more intuitive female-focused data.

The Evie offers menstrual cycle tracking, though it relies on user input to log periods and cycle length instead of using sensor data like skin temperature to predict cycles like Oura does. Although they both require separate subscriptions, we appreciated how easy it is to link Oura with Natural Cycles for additional health information.

Both the Oura 3 and Oura 4 offer the same tracking features as the Evie, plus they can additionally track body temperature, calories burned, comprehensive sleep data including latency and REM, blood oxygen, resting heart rate, and heart rate variability (HRV), breathing rate, respiratory rate, steps, and daily movement. Perks of the Oura 4: It exclusively detects sleep apnea, offers real-time stress monitoring, and cardiovascular overlays.

Oura's app receives updates fairly frequently, allowing users to update or edit their information and track their mood and meals.

Winner: Oura Ring 4

Sizing

Both rings are sized differently from standard ring sizing. Each company recommends that users order the specific sizing kits beforehand. Evie’s is complimentary, whereas Oura’s can be sent for free after the purchase of a ring or purchased for $10 from Target or Best Buy.

Winner: Evie Ring

Battery life and charging

When a wearable is specifically marketed to be worn during the night, it’s essential to have a long battery life.

The Evie Ring has a four-day battery life, depending on how long the ring is worn for. Its charger is portable and can hold over 10 charges—similar to AirPods.

The Gen 3 Oura Ring’s battery life stretches between five and seven days, depending on usage, but the device needs at least 20% battery life to record data overnight.

The Oura Ring 4 claims to be able to hold up to eight days of battery life—one more than the Oura 3. It also features a redesigned charging dock.

Our winner is …

The Oura Ring Gen 3

The first generation of any tech product is bound to have some glitches. We love the idea of the Evie Ring, and the portable charger is a game changer, but when it comes to battery life, color options, and reliable data, the Gen 3 Oura Ring is still our top smart ring pick.
