The world of wearable technology is undergoing a quiet revolution. While smartwatches have dominated our wrists, a more discreet and focused category of device has emerged: the smart ring. In 2025, this battle for your finger is heating up, with the established pioneer, Oura, facing its biggest challenge yet from tech giant Samsung and its highly anticipated Galaxy Ring. This guide breaks down everything you need to know to decide which ring will rule your wellness journey.
What is a Smart Ring?
A smart ring is a piece of jewelry packed with advanced sensors designed to be worn 24/7. Unlike a smartwatch, it operates without a screen, focusing on silently collecting high-quality biometric data—like your heart rate, body temperature, and movement. This information is then synced to a smartphone app, providing deep insights into your sleep, activity, and overall readiness to take on the day. Their long battery life and comfortable design make them ideal for continuous health monitoring.
The Reigning Champion: Oura Ring
Oura has long been the gold standard in the smart ring market, renowned for its precision in health and wellness tracking. The Oura Ring Gen3 is celebrated for its world-class sleep tracking, which analyzes sleep stages, heart rate variability (HRV), and temperature to provide a holistic “Sleep Score” and “Readiness Score.” Made of lightweight titanium, it's designed for comfort and durability. However, accessing Oura's full suite of analytics requires a $5.99 monthly subscription, a key factor in its business model.
The New Contender: Samsung Galaxy Ring
Samsung's entry into the market, the Galaxy Ring, leverages the power of its vast ecosystem. Priced at around $399, it's a premium device that promises seamless integration with Samsung Health, Galaxy phones, and even SmartThings for home automation. A major selling point is that it offers its deep health insights without a monthly subscription fee. The Galaxy Ring is designed to be thinner and lighter than the Oura, with a unique concave design to minimize scratches.
Health & Fitness Tracking: Data-Driven Insights
Both rings are powerhouses of health monitoring, equipped with sensors to track heart rate, blood oxygen (SpO2), skin temperature, and activity.
-
Oura is famous for its advanced sleep staging algorithm and readiness scores, making it a favorite among those looking to optimize their recovery and performance. It also offers specialized features like period prediction and illness detection.
-
Samsung counters with its own AI-powered tools, including a new “Energy Score” that digests your sleep and activity to gauge your daily energy levels. It also promises deep integration with Samsung Health to provide a unified view of your wellness.
Smart Features & Ecosystem Integration
This is where the two contenders truly diverge. Oura's strength lies in its focused, best-in-class health app and its compatibility with both iOS and Android.
The Samsung Galaxy Ring, however, is built to be the central hub of a connected lifestyle for Android users (it is not compatible with iPhone). It can integrate with the SmartThings platform to automate your environment, such as dimming the lights when it detects you're falling asleep. It's designed to work in tandem with the Galaxy Watch and other Samsung devices for a complete ecosystem experience.
