corpus-pairs.txt contains the final corpus of Android app pairs in the following format:
<free-version-apk-name>,<paid-version-apk-name>
popular-pairs.txt contains the subset of the corpus where the paid app had at
least 500,000 installations, according to its Play Store listing. It follows
the same format as corpus-pairs.txt.
This repository also includes full-page archival copies of the Play Store
listings for two apps we mention in our analysis of the most downloaded
paid apps: me.dreamsky.leagueofstickmanzombie and
se.magicinteractive.rumble. These archival copies were taken on
February 13, 2020.
