Name: Oura Ring 4 Review 2026: The Smart Ring That Tracks Your Health 24/7
Price: 244 GBP
Availability: InStock

The Oura Ring 4 is one of the most talked-about wearables of the year, and unlike a smartwatch, you barely notice you’re wearing it. Made of titanium with a fully round interior and recessed sensors, it tracks sleep, activity, stress, heart health, and blood oxygen levels 24/7, with battery life rated at 5-8 days depending on usage.

Health and Sleep Tracking

Using red and infrared LEDs for blood oxygen sensing, plus continuous heart rate and heart rate variability monitoring, the Ring 4 builds a detailed picture of your sleep stages, sleep score, and daily readiness. A digital temperature sensor also tracks trends over time, and an accelerometer covers activity and movement.

Design and Comfort

It’s built for 24/7 wear: lightweight titanium, non-allergenic, and comfortable enough that most users forget it’s on. It’s compatible with both iOS and Android.

The Honest Trade-Off

Here’s the catch: the ring itself is only part of the cost. Oura requires a paid membership (£5.99/month or £69.99/year, with a free first month) to unlock the full insights and features. If you don’t want an ongoing subscription on top of the hardware cost, factor that into your decision before buying.

Verdict

If you want the most discreet, comfortable way to track sleep and recovery and don’t mind a monthly fee, the Oura Ring 4 is one of the best smart rings available right now.
