In some ways yes. I tried my other halves smart watch and I alway had pain or small shocks. I had this problem with others I tried over the years. I even went this year for tests to see if I was allergic to certain metals which came back negative. With the ring no issues.
With the ring I downloaded an app on my phone. It gets paired with the ring. The app shows all my data...how much rem sleep, how much deep sleep, avg and lowest heat rate, avg and highest hrv, sleep disturbances, how much stress I had, heart rate, etc.
