Just wanted to ask a quick question about your piracy rates article…. posting here as there’s no comments on that article.
How do you distinguish between scores loaded from phones that purchased the app and those from phones that were authorized by the purchaser and synced via iTunes App?
For instance, there are 2 iPhones in my household and they each have different iTMS accounts and different iTunes profiles…. yet we are specifically allowed to authorize apps/music/etc purchased from iTMS for use on up to 5 devices. I often authorize and sync apps I’ve purchased on 1 iPhone to the other iPhone (my wife’s).
Depending on your methodology the second iPhone could show up as a pirated app user… ie: the purchasing deviceID would not match the deviceID of the phone submitting the score.
With up to 5 such syncs you could see an 80% ‘piracy’ rate just from this alone: 100 downloads x 5 devices = 500 app instances so 400 non-purchasing devices / 500 total devices = 80% non-purchasing device score submissions.

Do you account for this? Just curious.
We’re looking for changes in the binary by the pirating process. So as long as your apps were downloaded from iTunes, they’ll all look legit.
