Hello is a great app. An app I have been needing but was not out there. Not only do people make less phone calls these days, but you also want to receive fewer phone calls. And so, for that small time quota you have for phone calls, it is amazingly offensive that that time might get taken by phone calls that are strictly in the unwelcome category. This app solves that huge problem. If Facebook does not know who you are, you are suspect. That is a fair assessment. Much of the world does not have ID, no Social Security number, no credit history, nothing. A Facebook ID is a good start.
Knowing who is calling you is much welcome information. You can run from Facebook, but you can not hide.
Hello is an awesome app. I read about it in the news and installed it not long after. Heck, that is how I signed up for LinkedIn. I read about it in the news. And then I did not use it much for almost a decade. But Hello I am using.
