That's super cool that you can use it with your fitbit! And everything you're saying makes total sense... you may have convinced me, lol

I still have the free version (for now) but noticed that yesterday, it was unable to get a good reading. I tried about 3 times in the afternoon (one after the other) and just couldn't seem to get it to work (I got a lot of "Signal stabilizing" messages) - and then again ~3 times at night.

Have you ever seen that happen? Before that, it was working great - I wasn't really having any problems as long as I held still. I'm not sure what happened, I even tried taking the case off of my phone. No luck

Have you found anything interesting that helps/hurts your numbers? Have you experimented? I was curious yesterday because I was SOOOOOO STRESSED (like feeling like my head was going to explore) during the day, and then I went and worked out (and hit the sauna) and wanted to see how it affected me

And that's a neat idea about bringing it to the doctor!

Thanks!
