Purchased it to get rid of ads, and then there are ads to upgrade the service almost every time I use it. Your ads, other people's ads, it's still ads. I won't give them money again because they seem to just want more. Too bad.
Even though I paid money for this version, so saturated with ads for other services that it's now annoying to use and so might as well have got the free version.
Using this on the Nexus 6P, even I was a bit skittish on this app's accuracy. Today at the doctor's office I checked while waiting; app was within 2 bpm of what the nurse subsequently measured. 👍
5+ stars there is no other app. better than this one .
I paid for this app and now it's asking for me to upgrade again. Awful!
