Oura Ring 5 review: a stunning generational leap for smart rings
The Oura Ring 5 is a significantly smaller and lighter smart ring that aims to match the size of conventional jewellery while retaining comprehensive health‑tracking capabilities. It retails from £399 and requires a monthly subscription for full access to its metrics, positioning it as a premium wearable. Battery life has been extended to up to nine days, and the device offers sensors for heart rate, blood oxygen, temperature and motion across multiple health domains.
- ▪The Ring 5 is about 40% smaller in volume than its predecessor, measuring just over 6 mm in width and weighing around 2 g.
- ▪Full functionality beyond basic daily metrics requires a £5.99 per month subscription.
- ▪Battery life ranges from six to nine days depending on size, an improvement of roughly two days over the Ring 4.
- ▪The ring includes PPG sensors for heart rate and SpO₂, a temperature sensor, and an accelerometer to monitor sleep, activity, readiness, stress, resilience, heart and women’s health.
