The Oura Ring 4 has reached its lowest ever price on Amazon during Prime Day, now available for £232, down from £349. This represents a £117 saving on the advanced health-tracking ring, which has been reduced following the launch of the fifth-generation model last month.
Features and Health Insights
The Oura Ring 4 offers a range of smart features including meal and glucose tracking, designed to help users understand how diet affects overall health. It also tracks sleep, activity, and stress levels. A notable addition is the cardiovascular age insight, which compares users' heart health to their chronological age to promote longevity-focused choices.
Unlike many fitness trackers that have historically focused on male-centric metrics, the Oura Ring 4 includes comprehensive women's health insights. Its cycle tracking feature provides health and training tips based on the user's menstrual cycle phase, using temperature deviations to accurately predict and visualise monthly cycles.
Sleep Tracking and Temperature Detection
The ring is particularly acclaimed for its sleep tracking capabilities, delivering detailed data on sleep stages and quality. It can detect changes in body temperature that may indicate the onset of a cold, offering early warnings for potential illness.
According to a reviewer for The Standard, the Oura Ring is the most useful wearable tech they have tried this year, noting its ability to track immune function, stress resilience, and provide reminders to prioritise sleep. The reviewer also highlighted the Cycle Insights feature, which syncs seamlessly with apps like Natural Cycles to calculate daily fertility status.
Prime Day Availability
The Oura Ring 4 is available in multiple styles to suit personal aesthetics, and the current Amazon Prime Day deal offers the lowest price ever seen on the device. The ring is priced at £232, down from its original £349.
