The Today tab highlights information based on the time of day, and it includes shortcuts where I could quickly view the latest readings for things such as my sleep, activity, heart rate, stress or my readiness for the day. These at-a-glance metrics are easy to digest and helpful to look at when I had a quick minute throughout the day.
I also enjoyed looking at my reading at a more granular level in the Vitals tab. There's a lot to learn and decipher. Oura shows you nearly 20 different data points about your sleep alone. Even so, the company does a nice job breaking down all of these concepts in simple language. I wasn't familiar with the term latency, for example, but the app taught me that it's the amount of time it takes to fall asleep.
