The Best Smart Rings for Style, Health & Tech Lovers in the UK- 2025

Smart rings have evolved into sophisticated wearables that seamlessly blend style with functionality, offering users a discreet means to monitor health metrics and enhance daily life. These compact devices, typically worn on the finger, are equipped with sensors to track various health indicators such as sleep patterns, heart rate, and activity levels.

The best smart rings of 2025 showcase advancements in biometric technology, providing users with deeper insights into their well-being. Whether you’re a fitness enthusiast seeking detailed analytics or someone interested in subtle health monitoring, there’s a smart ring tailored to meet your needs.

What are Smart Rings?

Smart rings are sleek, wearable devices designed to track and monitor various health metrics discreetly. Unlike traditional fitness trackers or smartwatches, these rings are compact and lightweight, offering a more subtle alternative for users looking to keep tabs on their well-being without the bulk of larger devices. Equipped with advanced sensors, smart rings can monitor heart rate, sleep patterns, activity levels, and even stress. Some models are also capable of providing real-time health insights and notifications, making them an ideal choice for those looking for consistent, non-intrusive tracking.

Beyond health monitoring, smart rings can also integrate with other devices, such as smartphones, allowing for features like notifications, fitness goal tracking, and even controlling smart home systems. With their minimalist design and powerful capabilities, smart rings have become a popular option for tech-savvy individuals who prioritise both health optimisation and convenience in their everyday lives. Now, let’s look into the top Smart Rings of 2025 so far.

Oura Ring Gen 4

I’ve been using the Oura Ring Gen 4 for months, after upgrading from the Gen 3, and it’s transformed how I approach my health. Made from lightweight titanium with a non-allergenic, non-metallic inner molding, it’s so comfortable I forget it’s on. It lasts up to 8 days on a charge, and recharges in 20–80 minutes. It’s water-resistant to 328 feet, works with iOS and Android, and comes in sizes 4 to 15. It’s even FSA and HSA eligible.

The magic is in the insights. Instead of just giving me a readiness or sleep score, it explains why I got it. I can see when my heart rate dropped, how late meals or workouts affected my sleep, and how stress trends impact my recovery. The app combines daily data-like last night’s rest and yesterday’s activity-with long-term trends that reveal my cardiovascular age, resilience, and overall wellness trajectory.

At $350 plus a $72 annual subscription, it’s an investment. But for me, the detailed, actionable guidance has genuinely improved my habits. If you want both short- and long-term health tracking in a sleek, comfortable package, it’s worth it. For basic tracking without a subscription, consider the Ultrahuman Ring Air or Galaxy Ring.

Samsung Galaxy Ring

Samsung’s Galaxy Ring, released last July, is the first smart ring from a major tech brand, and it’s designed exclusively for Android users. I’ve been using the Galaxy Ring for a while, and I think it’s a solid option for anyone deeply embedded in the Samsung Health ecosystem. Made from titanium, it’s sleek yet durable, with a 10ATM waterproof rating that makes it safe for swimming. The battery lasts for up to seven days, and charging is done through a convenient charging case. It comes in sizes 5 to 13, and is FSA and HSA eligible.

What I love about the Galaxy Ring is its simplicity. It tracks sleep, activity, and stress in an easy-to-understand format, delivering sleep and readiness scores that tend to be higher than other smart rings I’ve tried-perfect if you want a less stressful approach to tracking your health. The real standout is the unique feature that allows you to take photos just by pinching your finger and thumb while wearing the ring. However, it’s important to note that iPhone users can’t use this device, as it’s not compatible with iOS.

The Galaxy Ring is ideal for Android users, especially those who already own a Galaxy Watch. If you’re looking for more comprehensive long-term health data, though, I’d suggest considering the Oura Ring 4.

Ultrahuman Ring Air

The Ultrahuman Ring Air is a fitness enthusiast’s dream, offering features that rival the Oura Ring without the need for a subscription. Made from titanium coated with Tungsten Carbide Carbon, it’s durable and sleek, available in colours like matte grey, aster black, space silver, and bionic gold. With water resistance up to 330 feet, it’s ready for any adventure. The ring’s battery lasts up to six days, and it uses Bluetooth Low-Energy for efficient connectivity. It’s also FSA and HSA eligible.

What stands out to me is its bio-hacking capabilities. The Ultrahuman Ring Air isn’t just a sleep tracker-it’s a full-day optimisation tool. From reminders for caffeine intake to when to get sunlight or wind down before bed, it helps me optimise my energy throughout the day. I particularly love the Cardio Adaptability feature, which is similar to Oura’s Cardio Capacity feature.

The readiness and sleep scores are incredibly similar to the Oura Ring, but the real selling point is that there’s no subscription fee. Ultrahuman’s primary audience is hardcore fitness enthusiasts and biohackers, but it also suits those looking for innovative features without ongoing fees.

If you’re just starting your fitness journey, though, it might feel a bit too intense.

RingConn Gen 2 Air

The RingConn Gen 2 Air is a perfect entry-level health tracker, offering great features without the hefty price tag. Made from titanium, it’s durable and lightweight, and its battery lasts an impressive 10 days, which is the longest on this list. With an IP68 waterproof rating, I can wear it confidently in the shower or pool. The charging case is convenient, and it’s FSA and HSA-eligible.

What I love about the RingConn Gen 2 Air is its approach to health tracking. Unlike more expensive smart rings, it doesn’t include a readiness or recovery score. Instead, it gives you an overall Wellness Balance by factoring in sleep score, stress/relax status, vitals score, and activity score. It’s a more holistic way to track your health, and it’s perfect for those who are casual exercisers but still want to keep tabs on their fitness and sleep.

It’s also a great option for people who wear a smartwatch during the day but want a smart ring just for sleep tracking. However, the user interface feels a bit basic compared to the Oura Ring 4 or Ultrahuman Ring Air. If you’re after more advanced features and data illustrations, those might be better choices.

Choosing the Right Smart Ring: A Comprehensive Comparison

In conclusion, each of the smart rings reviewed-Oura Ring Gen 4, Galaxy Ring, Ultrahuman Ring Air, and RingConn Gen 2 Air-offers unique features suited to different user needs and preferences.

The Oura Ring Gen 4 stands out for its in-depth health insights, including sleep, readiness, and long-term trends, making it ideal for those serious about optimizing their overall well-being. However, its premium pricing and subscription model may not appeal to everyone.

On the other hand, the Galaxy Ring is perfect for Android users, particularly those within the Samsung Health ecosystem. Its simplicity and seamless integration with Samsung devices make it a solid choice, though iPhone users are left out.

The Ultrahuman Ring Air appeals to biohackers and fitness enthusiasts, offering advanced tracking features, including a unique Cardio Adaptability function. Its subscription-free model is a major perk, though it may feel a bit intense for casual users.

Finally, the RingConn Gen 2 Air offers a more budget-friendly entry into smart ring technology, making it perfect for casual exercisers or those looking for a no-fuss sleep tracker. While lacking advanced features like recovery scores, it’s an affordable option with excellent battery life.

Ultimately, the best choice depends on your fitness goals, tech ecosystem, and willingness to invest in advanced features.
