The best thing about AppGrowing Global was that it's a free application to use and provides you with valuable insights into your competitors' ads performance. It can also be integrated into Google AdWords account in order to get more targeted information. App growing global doesn't provide any other services apart from viewing competitor advertisements so I do not recommend them too much if they are only looking out to view their competitors campaigns as well. As of now I think this tool lacks many things such as integration with Facebook or twitter advertising campaign management etc. but that may change later depending on how fast they develope new features. We had been using Appgrowing for a while to learn more about our competitors' strategy and see what kind of keywords we were ranking for when no one else knew!
