4 Best Smart Rings 2025 in the UK

The Oura Gen3 Horizon Smart Ring stands out with its comprehensive health tracking capabilities, including monitoring sleep, heart rate, and fitness levels. It's particularly noted for its accuracy, leveraging your finger for precise pulse readings. This makes the health data very personalized and reliable. The ring is compatible with both iOS and Android devices and can sync with over 40 popular apps, enhancing its utility for users who already use health tracking apps like Apple Health or Strava. This broad compatibility is a significant plus for those embedded in the Apple or Android ecosystems.

Another strength is its impressive battery life, lasting up to 7 days on a single charge, which minimizes the hassle of frequent recharging. The ring’s design also deserves mention; made of titanium, it's durable, lightweight, hypoallergenic, and water-resistant. This makes it suitable for continuous wear during various activities, from workouts to social events, without being intrusive or uncomfortable.

However, there are some drawbacks. Firstly, the ring requires a membership for full access to its features, costing GBP 5.99 per month after the first free month. This ongoing cost could be a deterrent for some users. Additionally, the sizing process is slightly cumbersome as it necessitates purchasing a separate sizing kit before getting the actual ring. This extra step might be inconvenient for those looking for a straightforward purchasing experience. Despite these minor inconveniences, the Oura Gen3 Horizon Smart Ring is a strong contender in the smart ring market, especially for users serious about their health tracking and who value a sleek, comfortable design.

The Amazfit Helio Ring is a compact and lightweight smart ring designed for those keen on tracking their health and fitness. One of its standout features is its comprehensive health tracking capabilities, including advanced sleep monitoring and heart rate variability tracking, which can provide valuable insights into your well-being. The inclusion of EDA (electrodermal activity) monitoring for stress adds another layer of health data, potentially helping users manage their mental health more effectively.

It's particularly useful for fitness enthusiasts, as it provides specialized fitness data and insights through the Zepp App. Another strong point is its design and comfort. Made from skin-friendly titanium alloy and weighing less than 4 grams, it's incredibly lightweight and comfortable to wear, even while sleeping. The 10 ATM water resistance means you don’t have to worry about taking it off for showers or swimming, adding to its convenience.

The battery life, at up to 4 days, might be shorter than some users would prefer, especially for those who are used to longer-lasting wearable devices. Another potential drawback is the reliance on the Zepp App for accessing detailed data and insights, which might be cumbersome for users who prefer a more straightforward experience. Additionally, the absence of a display could be a downside for those who like to view their stats directly on the device. The Amazfit Helio Ring is well-suited for health-conscious individuals and fitness enthusiasts looking for an in-depth, holistic tracking experience in a compact form. Its strengths lie in its advanced tracking features and comfort, while potential drawbacks include its battery life and app dependency.

The findtime Smart Ring is a lightweight and stylish option for anyone wanting a discreet fitness and health tracker on their finger. Weighing just 4.4 grams, it’s designed to be comfortable and non-intrusive during workouts or daily wear. Its stainless steel build looks modern and holds up well against rust and stains, making it easy to maintain.

In terms of health tracking, the ring covers key basics like heart rate, blood oxygen levels, and sleep quality by using optical and motion sensors. It also tracks daily steps, calories burned, and distance, supporting various sports modes such as walking, running, and cycling. This makes it a good fit for users interested in general fitness monitoring rather than advanced medical-grade data. The device connects via Bluetooth and works smoothly with both Android and iOS through a dedicated app, offering detailed charts and easy data review. However, it does not have GPS, so location-based tracking is unavailable, which might be a downside for runners or cyclists who want route mapping. Battery life is not explicitly stated, but with a lithium-ion battery and regular data syncing, users can expect typical smart ring endurance lasting several days before needing a recharge.

The small size might make it tricky for some users to operate or read notifications if that’s a priority, as it primarily focuses on health and activity data rather than smart features like calls or messages. This ring is well suited for those looking for a simple, comfortable health tracker that keeps an eye on fitness and sleep, especially if you prefer something less bulky than a smartwatch. While it lacks comprehensive smart features or GPS tracking, its accurate health sensors and stylish design make it a solid everyday fitness companion.
