I am a PhD student in Economics who is starting a new research project on the mobile app market. For this project, I would ideally need historical data on the rankings (or downloads), prices, and reviews of all the apps in the Google Play/iTunes store. For example, I would like to see the daily/weekly ranking (or downloads) of Angry Birds in the "games" category in the iTunes store from the time it launched until today, as well as its price over that period.
I am aware that appannie.com and other internet marketing have such data, but they are geared towards businesses and are therefore prohibitively expensive. They also don't seem to have a program of sharing their data with researchers (I asked).
Is there anyone who has such data and would be willing to share it with me? It will be properly cited an attributed, and I will not use the data for any project except in an agreed-upon way.
