Hi HN,
I spent this Labor Day weekend working on an idea I have had for a while. I just published it to Github and would really appreciate if people helped contribute.
The project can detect what libraries/sdks are being used inside applications that you have installed on your device. Ever wonder what advertising networks Angry Birds uses to monetize? Well now you can find out!

Thinking out loud: what could be nice would be to use what you have done to collect a related libraries database and then maybe build a recommender system. According to its personal project one could on your website and see what tools are commonly used with what he already use. An hypothesis: if you drive enough traffic to paid libraries or services (for example I have seen that Udacity used Mixpanel which is paid), maybe those people would be willing to pay you for helping the discovery of their product.
