The Oura Ring has become a standout in the world of smart wearables and fitness trackers, but with the recent release of the Oura Ring 4, many are left wondering whether it’s worth upgrading from the Oura Ring 3.

Both models offer impressive health tracking features, but the Oura Ring 4 steps up its game with better design and sensor accuracy, making it a solid choice for fitness enthusiasts.

In this Oura Ring 3 vs 4 comparison, I’ll share my verdict on which ring comes out on top and break down their features and performance to show you how they stack up. Without further ado, let’s dive into the comparison!

Oura Ring 3 vs 4: The Verdict

Oura Ring

Oura Ring 4 wins!

In the battle between the Oura Ring 3 and the Oura Ring 4, the clear winner is the Oura Ring 4.

Not only does it offer refined health tracking precision, but it also comes with a longer-lasting battery and a more ergonomic fit — raising the bar for smart rings and making it a standout option for users looking to stay on top of their health and wellness.

So, splurging an extra $100 for the Oura Ring 4 would definitely be a smart move!

However, the Oura Ring 3 remains an excellent choice for those who prioritize affordability and still want a capable health tracker without the new frills.

Now, let’s take a look at where each model excels. If you, however, want a more detailed technical comparison, read on to the next section to examine the key differences between the Oura Ring 3 vs 4.

Best Overall: Oura Ring 4

The Oura Ring 4 takes the crown as the best overall smart ring due to its advanced sensors that offer 30% improved accuracy in blood oxygen readings and better heart rate monitoring. Not only does its all-titanium construction boost durability, but it also delivers a stylish look that attracts users who want both function and flair. While the Gen 3 is still commendable, it simply cannot compete with the advancements made in the latest model.

Best Budget-Friendly: Oura Ring 3

For those on a budget, the Oura Ring 3 remains a fantastic option. It’s priced way lower than its successor and offers many of the same core features like sleep tracking and activity monitoring. While it may lack some of the advanced functionalities of the Oura Ring 4, it still delivers solid performance for users who don’t need cutting-edge technology.

Best Fitness Tracking: Oura Ring 4

When it comes to fitness tracking, the Oura Ring 4 really stands out with its automatic activity detection and improved heart rate monitoring. It fits better to different finger shapes and movements, giving you more accurate readings during workouts. This makes it a perfect sidekick for fitness enthusiasts wanting to level up their training routines.

Best Health Monitoring: Oura Ring 4

The Oura Ring 4 stands out in health monitoring with its upgraded sensors that give you more reliable data on sleep quality, recovery metrics, and daily readiness scores. Its knack for tracking physiological signals accurately helps users make better choices for their health and wellness routines. While the Gen 3 still delivers decent health insights, it falls short of the precision found in its successor.

Best Design: Oura Ring 4

In terms of design, the Oura Ring 4 is a clear winner with its fully titanium construction that not only looks elegant but also feels more comfortable on the finger. The removal of raised sensor bumps enhances usability, making it easier to wear throughout the day and night. While both rings are stylish, the Gen 3’s design feels less refined compared to the sleek finish of the new model.

Best Battery Life: Oura Ring 4

With an impressive battery life of up to eight days, the Oura Ring 4 outperforms its predecessor by offering longer usage between charges. This improvement means less hassle for users who want continuous tracking without frequent interruptions. The Gen 3’s battery life is commendable but simply cannot match the longevity provided by the latest version.

Best for Casual Users: Oura Ring 3

For casual users who want basic health tracking without a hefty price tag or subscription fees, the Oura Ring 3 is still a strong contender. It provides essential features like sleep analysis and activity tracking without overwhelming users with advanced metrics they may not need. This makes it a practical choice for those who are new to wearable technology or prefer simplicity over complexity.
