Are you a mobile app developer who's created this cool new app and are wondering how to promote it? Planning to upload a Filmed recording of your apps functionality as you demo it step by step and upload it to YouTube? 
Before you decide to act on the aforementioned steps you need to consider Vungle, which we had featured earlier. 

Most of us judge a movie by its trailer. No matter how many posters we come across or read reviews by best of critics, we always come back to YouTube.

Similarly, when we are about to download an application on our smartphone, the best we can do is check out the screenshots, read the description, and read reviews by those who've already downloaded it. Now, wouldn't it make sense to simply check out a video to see what the app is all about?

I am sure a lot of mobile application developers would love to have a platform where they can interactively describe the app created by them.

A start-up called Vungle is here to bring such a platform to mobile app developers. "Vungle addresses one of the major marketing problems facing mobile application developers and customers alike: discovering how the app really works before you download." shares Vungle's press release.
