Sorry, I just don't understand the motivation for a chat app that is desktop only.

And while we're at it, I also don't understand the motivation for a chat app that is Android only.

Personally, I prefer Android but I have friends, family and colleagues who don't so a chat app that doesn't support half my acquaintances is a non-starter.

Am I missing something? Isn't the smartphone now the most popular computing and communication device on the planet?
