I couldn't work out what the hell the app is from the website, as the home page tells you it's a "New Home for Work Chat" and mentions "Still using personal chat apps for work conversations?" - so I'm guessing it's supposed to have some business focus, but the app name makes it sound like something you'd install for your kids. I can't imagine ever saying to someone "we need to discuss contract details, let's talk on BirdyChat".

It just sounds—let's say—too playful.

Specially if you go to the homepage and they're trying to market it as a work too.. If I went to my boss and tried to make the case that we should move all of our encrypted communication from Whatsapp to something called BirdyChat they would laugh at me and dismiss the idea.

That might just be me, not sure.

Personally I hate the name because it reminds me of https://en.wikipedia.org/wiki/Birdy_Nam_Nam (whose work I like)

Twitter. Also it could mean penis (in some places).
