Apple Watch Heartrate Monitor On Par With Human Expert

I gave blood today. No need to thank me, I did it for the free snacks and t-shirt. But seriously, it was an opportunity to get my heart rate measured by an expert and compare it to my Apple Watch. The good news? Both the watch and the American Red Cross nurse said my heart rate was fine. The nurse measured me at 68 Beats Per Minute and my Apple Watch measured 67 BPM, which is well within the margin of error. So I've got that going for me!

Actually, it was a little harder than it should be. There is no app you can launch that just displays your heartbeat. You either have to swipe through the 20 or so "Glances" views to find the Heartrate monitor view, or use the Workout app, which I did. I launched the Workout app on the watch, and specified "Indoor Walking" as I had to choose something. There are quite a few options... Indoor or Outdoor Walk, Run or Cycle, Elliptical, Stair Stepper, or Rower as well as Other. I also had to remember to turn off the Workout when I was done, otherwise it would indefinitely measure my blood pressure. I could tell this because the green sensor light under the watch was on continuosly. I could see how this could effect battery life. Perhaps Apple should offer a dedicated Heartrate Sensor app, and consider offering a sleep or shutdown timer for the Workout app.
