Here are the top 5 things you need to know about how the Oura Ring 5 just got a major update that could change your sleep tracking forever.
- FDA clearance for AFib detection: The biggest update is the ring's ability to detect signs of atrial fibrillation (AFib). This feature, powered by a new algorithm, moves the Oura Ring 5 from a wellness gadget into a legitimate medical-grade heart health monitor for millions of users.
- Automated activity heart rate tracking: Finally, the ring will automatically start a heart rate session when it detects a walk, run, or bike ride. No more manually tapping "Start Activity" in the app—the ring now knows when you're moving and logs the data live.
- A new "Cardiovascular Age" metric: The update introduces a "Cardiovascular Age" score. By analyzing your resting heart rate, HRV, and activity patterns, the Oura Ring 5 gives you an age for your heart's health relative to your biological age, making it a powerful motivator to improve your lifestyle.
- Better sleep staging with "Sleep Staging 2.0": Sleep scores are now more accurate thanks to a refined algorithm that combines motion, heart rate, and temperature data. You'll see a clearer distinction between light, deep, and REM sleep, with fewer "awake" moments mistakenly logged during sleep.
- Expanded compatibility and price hold: The firmware update is completely free for all existing Oura Ring 5 users and works with both iPhone and Android. Despite adding FDA-cleared features, the ring’s $299 starting price remains unchanged, making it a more obvious choice for anyone serious about health data.
