I love my Oura Ring 4. It’s one of the few wearables I have on me continuously. I appreciate many of its features, from its sleep-tracking prowess to its automatic exercise recognition. It won’t push my Garmin watch off my wrist for active training, but for anything else, I often recommend the Oura to anyone unsure which wearable to choose.
Despite its many excellent qualities, the Oura's smart ring system has one big flaw: stress tracking. Stress is one of the big factors that the algorithm takes into consideration when calculating how well you’ve recovered and how well you’ve slept. It even affects how the app evaluates your diet.
