Great device. Only thing I don't like is the minute you open the app to take a reading you get an ad to buy upgraded service. I understand business side of medical devices, but everytime! Once or twice a week is plenty. It gets to the point you know it is an ad and you click out before even reading. Again very helpful device for piece of mind, and worth the money.

Unit is ok, but not great. Doesn't do a good job for people with tremors such as Parkinson's or Essential Tremors. It can be hard to get a stable reading. Also, have had issues with schmutz getting into the battery compartment. Then, even though it shows 66% battery level it failed to get a reading. I clean out the gunk and it works fine, with the old battery. And while I'm being picky, why did they pick a coin cell size that seems to be rare instead of a ubiquitous size like 2032?

App freezes after login on 2 different devices. We have 2 Androids (Samsung Galaxy and Google Pixel). On both phones, I install the app, login with my existing account, and then get a permanent solid white screen that never takes me to anything. I tried: closing and reopening, force closing and reopening, uninstalling and reinstalling, rebooting phone then opening, all with the same results. Since the product can't be used without a phone, this makes the product I just bought useless.
