I've been using this app for quite some time now and I must say it's one of the best messaging apps out there. It's simple, easy to use, and has all the essential features I need. The best part is that it's completely free and doesn't have any annoying advertisements. The only thing I would suggest is to add more customization options for the chat interface. Other than that, it's a great app!
