Oura Ring Gen 3 Review: 8.4/10 - Discreet sleep and readiness tracking on your finger

8.4/10

Overview

The Oura Ring Gen 3 is a smart ring that packs advanced health-tracking sensors into a discreet, lightweight titanium ring. Launched in November 2021, it tracks sleep stages, heart rate, HRV, body temperature, and activity, providing daily Readiness and Sleep Scores. Its minimalist form factor makes it an appealing alternative to wrist-based wearables for those who prefer not to wear a watch to bed.

Design & Build

The Oura Ring Gen 3 is available in several finishes including Silver, Black, Stealth, Gold, and Rose Gold, with a titanium construction that is both lightweight and durable. The ring weighs between 4 and 6 grams depending on size, making it comfortable for 24/7 wear including during sleep. The inner surface contains the sensor bumps that contact your finger, while the outer surface is smooth and looks like a regular fashion ring. The 100-meter water resistance rating means it can be worn swimming and showering. Sizing is critical, and Oura provides a free sizing kit before purchase.

Performance

Sleep tracking is the Oura Ring’s standout capability, with detailed analysis of light, deep, and REM sleep stages along with sleep efficiency and restfulness. The Readiness Score combines sleep quality, HRV, resting heart rate, and body temperature to tell you if you are recovered enough for a hard workout. HRV measurements correlate well with medical-grade devices. The temperature sensor detects trends that can indicate illness onset or cycle changes. Activity tracking includes step count, calories burned, and activity categorization. Battery life reaches a consistent 4 to 7 days depending on ring size and usage.

Features

The Oura app provides a clean, intuitive interface with daily Sleep, Readiness, and Activity Scores. In-app content includes guided audio sessions for sleep and meditation. Workout heart rate tracking was added post-launch. The temperature trend monitoring can detect early signs of illness. Cycle tracking integrates with Natural Cycles for fertility awareness. Third-party integrations include Apple Health, Google Fit, Strava, and Natural Cycles. Oura membership is required for personalized insights, daily scores, and detailed data analysis.
