The Oura Ring is, in my opinion, the sleep and health tracker to rule them all. Not only does it track your sleep, stress, activity, and more, it also creates helpful data illustrations that encourages healthy habits, whether that's a consistent bedtime routine, daily activity, or reduced alcohol consumption. Many users, myself included, have reported changing their drinking habits after seeing their heart rate's response to a few beers late at night on Oura's graphs. Earning high sleep scores after several nights of consistent sleep has encouraged me to aim for a regimented bedtime routine, and now I wake up at the same time every day without an alarm. Needless to say, the Oura Ring works. Oura's data capture and illustration is extensive, so I'd recommend it for those who want to get into the weeds of their health data (and not recommend it for those who would be freaked out by data overload or who have a history of health anxiety). Oura provides scores everyday for sleep, readiness, and activity. You can see your stress for the day laid out on a graph that ranks it from restored, relaxed, engaged, or stressed. Its Resilience feature then takes the data it gathers through Daytime Stress and calculates how well or poorly you bounce back from stress in general. Also: The best smart rings My favorite feature on the Oura Ring is Symptom Radar, which notifies wearers when the smart ring has detected strain and encourages wearers to rest. It has the potential to predict when you're getting sick, and it has done that a few times for myself. Oura is always developing new features, partnerships, and app upgrades that make the smart ring more useful. For example, it recently announced a partnership with glucose management brand Dexcom and launched a CGM integration for users looking to view their glucose levels and log their meals within the Oura app. Its partnership with hormone-free menstrual tracking app Natural Cycles has been a major draw for women looking for an alternative to prescription-free birth control. The major downside of the smart ring is its subscription fee, which, on top of the $350 smart ring will cost users $70 a year or $6 per month. If you think getting full access to your health data is worth it, the smart ring will provide you with plenty of information on your wellness and might even encourage further healthy habits.
