A investor wrote an article for TechCrunch with some general tips on investing into mobile apps. He starts off by saying that there are many apps in the iOS gaming category that are widely successful, but unfortunately it is also the most populated category. He then discusses the three other types of apps that can be successful in the non-gaming categories: camera apps, messaging apps, and apps that communicate with non-moblle devices. He also discusses how an app can piggyback off of another’s success. It may be worth reading for any beginners or intermediates to mobile app investing or development.
