    My wife loves her ring! She reminds me every week that it’s her favorite gift. It gives lots of information including sleep, cycles (ovulation), activity, etc. 10/10

    Amazing ring. Great stats on stress, heart health, sleep (with REM cycle observations), activity tracking/sensing/recommending, and activity sharing. There are great features this has that essentially replaced the need for a fitness watch. My only qualm is that mine within a month of use has had its battery deteriorate to losing charge within a day although it is estimated to last 7-8 days. So that’s a bit strange and inconvenient. Looking to see if this is just a software issue or a hardware that needs fixing

    Really insightful if you’re into health data! I also use Stelo to track my glucose and I love they are integrated together. Highly recommend wearing the sizing kit for 24-48 hours before purchasing!

    Since my wife was diagnosed with epilepsy the ring changed her life because oura ring notifies her about her stress levels and sends her a notification on the phone letting her know that she needs to calm down and that's helpful for me because I can't stay with her the whole time due to my work but now with the ring we are able to control a little bit more her symptoms
