Oura Ring Vs. Fitbit: Side by Side Comparison

Tracking our health and fitness nowadays has become the trend these days. Especially if you want to lead a healthy lifestyle, you might need to invest in a reliable fitness and health tracking device. Although the market is flooded with fitness trackers, Oura Ring and Fitbit trackers are among the best out there.

This article tries to unpack the main differences between Oura Ring and Fitbit, the leading brands in the fitness tracker world.

Appearance, Design, and Comfort

The Oura Ring is a fitness tracker that comes in the form of a ring and doesn’t have a screen. It’s made of lightweight titanium that makes it super durable. This tracker is comfortable to wear, but it’s chunkier compared to a normal ring. The ring comes in two versions: Heritage and Balance. Although they have different looks, the features are the same.

On the other hand, Fitbit is designed to fit on the wrist. However, there are different-sized smartwatches and fitness bands to choose from. Fitbit bands are easy to customize to suit your needs and style. Additionally, most Fitbit trackers are equipped with a display to help you monitor all your activities.

Activity and Workout Tracking

The Oura Ring doesn’t automatically record workouts and other activities and rarely notices strength workouts unless your heart rate spikes. It tracks the step count and the calories burned based on the elevated heart rate to your activity score. However, you need to enter the workouts manually.

If you want a workout tracker, then Fitbit is a great choice since it records your walks and runs automatically when it detects any movement.

The best thing about the Oura Ring is that it gives you a daily activity target that depends on your previous day’s activity, rest, and sleep quality. For activity tracking, Fitbit carries the day.

Calorie Tracking

The Oura Ring captures the calories you’ve burned while training, walking, or carrying out other physical activities. You need to wear the ring while exercising or engaging in physical activities; otherwise, the active calorie burn will be slightly off. However, the Oura Ring isn’t very reliable in calorie tracking.

Fitbit devices are equipped with a calorie-counting feature that allows you to track the calories burned based on the type of exercise. It uses the basal metabolic rate (BMR) and your activity data to estimate the calories burned.

Sleep Tracking

One of the most effective features of both Oura Ring and Fitbit is sleep tracking- and both have impressive systems. However, there are slight differences between them. Oura Ring is ideal for those looking for granular detail and more data. This ring gives a breakdown of your sleep stages (light, REM, and deep). It then generates your overall sleep score based on a range of breathing, temperature, heart rate, sleep efficiency, and more.

Like Oura, Fitbit has great accuracy and analysis of sleep. All Fitbit devices have automatic sleep monitoring, and those with heart rate monitors offer extra data with greater accuracy. Fitbit tracks your sleep duration, key sleep stages (light, REM, and deep), and time taken to fall asleep.

Heart Rate Monitoring

The Oura Ring and Fitbit track your heart rate, which is crucial to monitoring your health and readiness. The Oura Ring measures your resting heart rate and heart rate viability (HRV). If your resting heart rate rises for no reason, it can be a sign of injury, over-training, or sickness. Fitbit doesn’t have heart rate viability data and isn’t compatible with other HRV applications.

Blood Oxygen Level

The main difference between Oura Ring and Fitbit is that Oura Ring focuses more on health, sleep, and wellness monitoring. In contrast, Fitbit focuses on health and wellness like blood oxygen levels (SpO2) using the blood oxygen sensor.


The Oura ring comes with a sturdy constriction that can withstand water levels of up to 100 meters. This makes it ideal for various activities that involve water. On the other hand, most Fitbit devices have a water resistance of up 50 meters. They are swim-proof and can withstand even the sweatiest workouts.

Integrations / Compatibilities

Both Oura Ring and Fitbit can connect to Android and iOS devices. The Fitbit also connects with other Windows devices. The Oura Ring also has its own dedicated Android and iOS app, which helps you track metrics and your health over time.


Fitbit devices are available at different price ranges. You can find a Fitbit tracker for as low as $69.95 and can rise to $300 for advanced models. Conversely, the Oura Ring costs $340 for its Heritage and Balance design options. However, if you want something flashier, a diamond option goes for up to $1,137.

Battery Life

Fitbit promises up to one week of battery life. However, if you use features like the GPS and heart rate monitor, the battery life reduces. On the other hand, the Oura Ring has up to 1-week battery life and can charge in up to 80 minutes.

Does Oura ring have a monthly fee?

No. Once you purchase the Oura Ring, there are no monthly charges or additional subscription fees.

Is Oura ring worth the money?

The Oura Ring is a great fitness tracker. If you want accurate sleep and health data, go for the Oura Ring. However, it isn’t a good fit if you want to track your workouts and other physical activities.

Final Thoughts

Both the Oura Ring and Fitbit are reliable health and fitness trackers that can help you keep track of your fitness and health. However, the tracker you choose should entirely depend on your needs, style, and budget.
