4 stars: This app has been great!!! It has become exactly what I needed, (2 phone#'s-1device) and it works better than par. It has only stopped once. However, I wrongly presumed, that I would be creating a new contacts list within the app for my business customer's and contacts. Instead, my personal contact list was imported to the app. This was a major drawback, and a disappointment. .....I'm sure I'll find the right app for the job tho.
3 stars: Works Fine. I needed a second line for work but didn't want to bother with two phones. Google Fi and Google Voice don't play nice together on Google Pixel, so I went with this. It's a little more than is want to pay for how often I use it. Plus the interface is VERY basic. But, it does the job I want and I don't want to bother with switching right now.
4 stars: Works pretty well most of the time. Sometimes it completely logs me out. Often, a text message will show up on my list of text messages (previews), but when I click on that preview to read it, it's not in the conversation. Eventually it shows up, but usually it's way too late.
5 stars: I have been using it for over a year for my online business. The only issue I have with it is the caller ID is never accurate. I could be receiving a call from Pennsylvania but the caller ID will show some other states.
4 stars: It works for me and my business. I carry only one phone now. Really convenient. One annoyance is the contacts are not configured in a user friendly way ...
