All data and readings are shown on Oura’s smartphone app, which you’ll need to download to get the best out from it. You’ll also find suggestions and advice related to your scores: meditation if your sleep is out of whack, how to manage stress, readiness reports that will tell you how primed you are to take on draining activities like a long journey or a tough workout. It can even integrate with 40+ apps, like Apple Health, Google Health Connect, Natural Cycles, Flo, Strava and more so you can match up your data with your health goals – great if you’re training for something like a marathon.
