Finding a good application is a problem we have all run into at some point. There are so many applications in the Google Play store that finding the right one can take some time. This is especially true if you use multiple application stores. Apptro is attempting to make this easier by releasing an application to let people share their apps with others.
The premise is simple. You have an application that's awesome and someone needs to find an application like it. You share it and they download it. It is easy as that. There are a plethora of sharing apps out there. However, this one was initially geared for app stores that were hosted by Appia. Initially, it was only offered to customers of specific carriers in Europe. Since then, it was released on the Google Play Store and is available to any who can download it.
If you're talking about sheer functionality, nothing. Much like its competition, its function is quite clear. It allows people to share applications. What sets it apart is how Apptro accomplishes this. According to SFGate, Apptro uses Facebook's social graph. If you're unfamiliar with this concept, it's how Facebook determines your core group of friends.
To see it work, go to Facebook and look at the chat window. You should see some random people from your list, but you should also see the people you speak with the most. That includes those who are offline. This is Facebook using its social graph to determine your core group of friends. Apptro also uses this technology, so you only see applications that are shared by your core group.
It can also do a few other things. Apptro can determine how often you open an application and how much time you spend on it. It also keeps track of how much bandwidth each app uses and, if you have a data limit, helps monitor how close you are to your limits. Could this be the next wave in application discovery for Android? Let us know your thoughts in the comments. If you'd like to check it out for yourself, here is the Google Play Store link.
