Using pop up messages for a new user is a good way to take them through the learning curve

Its possible that you have created some revolutionary in your app and you want your users to give it a try but your previous version was, lets say, mundane and didn’t really move way from the usual path, in that case its a good idea to include some quick tips on your feature enhancements with the new version. Some touch and gesture related controls may go unnoticed by most users and as a result the App will come across as something that was never really worked on. Avoid that, go all out and tell the fellows what’s new in big and bold, in this case red or pink

Here’s how Flickr says things!
