What Is the Oura Ring 5 and Why It Matters
The Oura Ring 5 is a titanium smart ring that combines a thinner physical design with upgraded sensors and software to provide continuous, discreet wearable health monitoring focused on sleep, activity, and emerging health patterns. Oura calls it the world’s smallest smart ring, and the company says it is 40% smaller than the Oura Ring 4 while maintaining up to a week of battery life and an IP68 rating for dust and water resistance at depths up to 100 metres. To achieve the size reduction, Oura redesigned the ring’s mechanical, electrical, optical, battery, and sensing components, using lower‑profile sensor domes, more powerful LEDs, and 12 signal pathways to improve consistency on different fingers and skin tones. The goal is a smart ring design that disappears on the hand yet still feeds detailed biometric data into the Oura app.
Design Changes: Thinner, Lighter, Less Conspicuous
Oura Ring 5 features a noticeably slimmer silhouette than Ring 4, with smoother curvature meant to snag less on clothing and feel less bulky against adjacent fingers. According to PCMag, the company achieved a “40% smaller” design while keeping the titanium build and introducing a new physical vapour deposition coating to improve scratch resistance. Sizes range from 6 to 13, and Oura recommends its new sizing kit even for existing customers because the reshaped interior and reduced thickness may change how the ring fits. Despite shrinking the housing, the upgraded architecture keeps the sensor domes flatter while using stronger LEDs and 12 signal pathways to maintain reliable readings. For people who disliked the slightly chunky look of earlier models, the redesign focuses on being less conspicuous and more jewellery‑like without sacrificing week‑long battery life or durability in the pool or ocean.
Health Radar Tracking and New App Intelligence
The standout software upgrade among Oura Ring 5 features is Health Radar tracking, which builds on the earlier Symptom Radar to flag changes in long‑term biometrics. The first Health Radar tools are Blood Pressure Signals and Nighttime Breathing. Blood Pressure Signals watches for shifts that could point to cardiovascular strain, while letting members manually log cuff readings in the app so those values sit alongside Oura’s continuous data. Nighttime Breathing offers a 30‑day view of breathing patterns and disturbances during sleep, highlighting trends that might warrant a conversation with a clinician. Oura is clear that the ring is not a medical device and does not diagnose or treat conditions; the aim is early, proactive insight. For users, the practical value lies in seeing subtle pattern changes that basic step counters or single‑night sleep trackers would miss.
Live Activity, GLP-1 Insights, and Women’s Health Updates
Beyond Health Radar, Oura Ring 5 gains live activity tracking in the app, turning the ring into a more practical workout companion. You can start a session for running, cycling, or strength training and see real‑time pace and distance, including data relayed from supported third‑party heart‑rate straps via lock‑screen widgets. For people using GLP‑1 medications, GLP‑1 Insights combines medication logging, dose schedules, side‑effect tracking, weight changes, and Oura metrics like Sleep, Activity, Readiness, and stress into a single view over time. Women’s health features expand as well: Menopause Insights adds the Menopause Impact Scale to track effects on sleep, mood, cognition, and daily functioning, while updated Cycle Insights helps members on hormonal birth control understand how their biometric patterns vary between hormone and hormone‑free days. Collectively, these tools shift the ring from passive tracker to context‑rich health journal.
Charging Case, Pricing, and Is It Worth Upgrading from Ring 4?
Convenience gets a boost with a new portable charging case made from aluminium, which stores enough power for about one month of top‑ups and supports wireless charging. A button on the case checks battery status and helps pair the ring, and a new Locate feature in the app can find misplaced rings and cases starting from Oura Ring 4. The Oura Ring 5 is available in finishes such as Silver, Black, Gold, Stealth, Brushed Silver, and a new Deep Rose colour, with a free sizing kit offered before purchase. Ring 4 is now discounted as Ring 5 pre‑orders open, making the older model the cheaper entry point for core sleep and readiness tracking. The upgrade makes the most sense if you value a slimmer smart ring design, need Health Radar tracking and live activity metrics, or plan to use GLP‑1 and women’s health insights extensively.
