oura ring 4

Oura Ring 4 is the latest version of Oura’s smart ring, focused on more accurate health tracking, better comfort, and deeper insights into sleep, stress, and daily readiness. It builds on Gen 3 with a new sensing platform, more exercise tracking, and expanded wellness features in the app.

What’s New in Oura Ring 4

• A new smart sensing platform uses multiple light wavelengths and more sensing “paths” to adapt to your finger shape and skin tone for more accurate data day and night.

• Sensors now form an 18‑path multi‑wavelength PPG system, boosting accuracy for heart rate, HRV, respiration, and temperature trends versus the previous generation.

• Oura expanded automatic exercise tracking to 40+ activity types, showing intensity, calories, and time, and using phone GPS for pace and route when available.

Core Health & Sleep Features

• Tracks sleep duration and stages alongside detailed sleep scores and readiness, helping you adjust training and bedtime habits.

• Measures 24/7 heart rate, heart rate variability, respiration rate, movement, and temperature deviations to flag changes such as stress, illness, or recovery needs.

• Offers continuous blood oxygen (SpO2) sensing at night to highlight possible breathing or oxygenation issues during sleep.

App Experience and New Tools

• The app home shows readiness, sleep, activity, heart rate, and stress at a glance, with deeper drill‑downs for each metric.

• A new timeline view lays out your day—wake time, workouts, tags like meditation—so you can see how events relate to stress and recovery.

• “My Health” and vitals tabs organize long‑term trends, letting you swipe back through prior days to compare patterns over time.

Women’s Health, Stress, and AI Add‑Ons

• Cycle Insights now includes a Fertile Window view that uses temperature and cycle data to give more granular fertility timing information.

• Daytime Stress shows how moments of high or low stress line up with your movement, tags, and habits, making it easier to see what helps you recover.

• Some latest app features lean on AI, like meal‑related tools that analyze your plate from a photo and suggest better timing or structure for meals to support sleep and energy.

Early Forum & Review Buzz

• Tech reviewers generally call Oura Ring 4 one of the strongest all‑around health rings thanks to its improved accuracy, expanded activity tracking, and comfortable design.

• On social platforms and forums, users mention that the richer app can feel dense at first, but many still keep it for the depth of sleep, stress, and readiness insights versus watches.
