Flychat

It often happens for users to be using a particular application and to receive a message. The problem is that you might not want to close the app that you’re using in order to read or respond, and this is where Flychat comes into play.
 
With the help of this nifty app, users will be able to see when a message has been received and they will be able to respond without leaving the current application. A small info bubble is rendered on top of everything else, so it’s quite easy to respond.
 
For now, Flychat only supports the big messaging apps out there such as WhatsApp, Telegram and Hangouts.
