I love my Oura ring. www.ouraring.com
It tracks so many health points: sleep, respiration, activity, body temperature, heart rate.
It talks to my apple watch and my iphone combining all of my date to spit out a readiness score each day based on how I've slept, how I have recovered from exercise, my body temperature and heart rate variability.
The app does a spectacular job of explaining all of this to you with easy to understand charts and diagrams.
You will even get a weekly report of how you are doing overall.
I've been using it for 9 months now and use it as a general guide to what's happening in my body. If my readiness score is low I try to take it easy or get more sleep. Very interesting to see how a stressful day, a long run or drinking alcohol can really affect your daily readiness.
I'm a big fan. Check it out!
