The Oura Ring 5 debuted on June 4, 2023, marking a significant evolution in the wearable tech landscape. At just
6.09mm wide and
2.28mm thick, it is touted as the
world's smallest smart ring, weighing between
2 grams and 2.69 grams compared to its predecessor's 3.3 to 5.2 grams.
The size reduction has not compromised functionality; the new design incorporates a
rebuilt internal architecture with low-profile sensor domes and optimized signal pathways for enhanced accuracy across various skin tones. Oura emphasizes that nearly
50% of its users manage metabolic conditions, with many using medication to assist.
The Ring 5's upgraded features include tracking for
resting heart rate,
stress response, and
sleep quality, while boasting a battery life of
six to nine days. Users love the
Symptom Radar functionality, which notifies them of potential health issues early on. The
Oura app provides clear and engaging data presentation, further enhancing user experience.
Available in six finishes, the Ring 5 starts at
£399 and requires a
monthly subscription of £5.99, a price point that may deter some but reflects its elite positioning among health trackers. Oura has established itself as the health measurement device for
athletes and high-profile individuals seeking detailed physiological insights.
