I have never used this App but if I did I would also be uninstalling it right now. Chat/messaging apps are not primarily about features, they are about connections. They are social. I don't care if your chat app is awesome if none of my friends are on it.

I have been a long term supporter of Trillian for just that reason, cross platform support. It's quirky at times but it gives me as many protocols as possible in one place, and a combined list of all my friends through one interface. It also syncs across all my devices (multiple PC's and Android tablets/phones) As long as they keep that up they maximize the social connections... and my loyalty.
