Disclosed herein is a system and method for efficiently gathering information about applications for mobile communication devices (e.g., smartphones, netbooks, and tablets). This disclosure is also directed to a server producing assessments for applications by analyzing data from multiple sources. To gather information, a device sends information about an application to a server, which stores some or all of the information and may request additional information, if necessary. The server collects information from many devices, including devices that have varied configurations and different operating systems, by only collecting the appropriate information from each device. The server gathers the appropriate data to perform in-depth, granular mobile application analysis while minimizing overhead on devices, wireless networks, and the server. The server may collect portions of data from multiple devices, combining them on the server to produce an assessment for an application.
