Facebook recently released their dedicated messenger application for both Android and iOS devices. I’ve had a chance to play around with the Facebook Messenger app and find it quite nice to use as a dedicated application. Facebook does have plans to integrate with their official Facebook application but there is no timeline for when that will happen.
Download it and try it out for yourself:
