Google Duo - (seriously)?

I like Google duo because it allows me to FaceTime my friend who doesn’t have an iPhone like me. He has a “Google Pixel.” The reason I am writing this is because I got a message that says for ME to tell MY friends and family “happy holidays” on Christmas Eve. Are you going to call Christmas “Holiday?” It’s a real holiday and it’s been around for 2017 years 11 months and 24 days. You can’t say happy holidays on Christmas Eve timing it this way on purpose and talk as if there isn’t a holiday called “Christmas” literally a day later. If you’d like to know, 75% of Americans call themselves Christians so you aren’t really staying with the flow, and 33% of the world are Christians (which is the most popularly practiced religion), so you aren’t really staying with the flow, a lot. Im not going to “face-to-face say happy holidays with a FaceTime call.” I’m going to go out of town with my family to visit more family to say “Merry Christmas.” Don’t pull that crap, it made me mad and I bet it made Cloyd Rivers, the one who inspires me to make this sort of thing, pretty mad too. Merica.

Phenomenal call quality

Downloaded this app because I have ZERO cell service in my house and apple didn’t enable WiFi calling. So instead of stepping outside in the rain or freezing weather whenever someone wanted to call me at home, Duo has solved that. Call audio is the clearest I have ever heard on a phone call, like the person is on the other side of your phone talking at your ear. I have strong WiFi so I can’t say how it would perform if WiFi is spotty. I noticed that when you are not on WiFi and take a duo call over your cell service there is a bit of a delay between accepting the call and when the caller can hear you which can lead to some confusion, but still great call quality. Very simple interface, no bells and whistles, just works, and works great.
