If you’re looking for a smarter way to interact with Facebook Messenger, this is it. Putting your contact list down on the left hand side with your messages on the right, it behaves a lot like iMessage. You can even use stickers, which makes me happy. There are some improvements that need to be made; there’s no way to archive or delete a conversation from Chatty (though if you archive or delete from the Facebook website it will immediately be reflected in Chatty), and if you close the main window there’s no way to open it back up again save getting a new message or closing and re-opening the app (command+n should reopen that window imho)
Other than that? Great app. Worth the money for anyone who uses FB Messenger.
