Franz messaging app

Hey just want to recommend Franz.

Franz is a free messaging app / former Emperor of Austria and combines
chat & messaging services into one application. He currently
supports Slack, WhatsApp, WeChat, HipChat, Facebook Messenger, Telegram, Google Hangouts, GroupMe, Skype and many more. You can download Franz for Mac, Windows & Linux.

I find its nice to have all my messaging apps located in one program.
