I purposely wore the ring on my right index finger. I still write a lot of my stories by hand (old school, I know), so I wanted to see if it would bother me while holding a pen or pencil. It didn't. The ring is also designed to be worn 24/7 and is water resistant, and it didn't give me any trouble when I washed my hands or showered with it.
Another highlight was the Oura app. The company began rolling out a redesign of the app to all its users earlier this month, and I thought the layout of the app was very intuitive. Data from the smart rings is presented in three tabs called Today, Vitals and My Health.
