That's the bad news. ... The good news is that 2016 was the year I decided to take my health a little more seriously. Step 1: Get a doctor. That led to Step 2: Find out that I indeed had high blood pressure, and start dealing with that. And that led to Step 3: Keep track of how the ol' blood beater is beating on a daily basis.
So it was time to snag a blood pressure monitor. I started with your basic Amazon best-seller. And that was fine. It did the job, and it even had a little bit of smarts to it. But I wanted something even smarter, even more connected.
So I turned to Withings, whose connected scaled I'd already been using for some time. And their wireless blood pressure monitor has served me very well since I started keeping track of things. Probably as impressive as anything is that in the six months or so that I've been using it, I still haven't had to change out the batteries. (Which, strangely, was my biggest concern.)
This one works excellently with Android and Google Fit, as well as iOS and HealthKit.
