User reviews

App doesn’t work.

I’m not sure what the behavior of this app is supposed to be but logon fails and thus the app is a non starter. For me, this has been on going for at least 3 months and it is integral to the overall process and experience.

Terrible App

As CuttyNYC said 2 years ago;
The device is great, the app is terrible. I’m sad that the app has been this bad for over 2 years. That suggests they aren’t trying to make it any better.

Love this

I got worried when I saw a previous (and only) review but any bugs must have been fixed because this works perfectly. Love it!

Do not buy this

Totally useless. What a rip off. The app doesn’t pair the device. I will try to return my device. This is a CON.

Worked great, now crashes on launch

8/18/2023 update shows logo for a couple of seconds then crashes.
