I want to delete free apps from my Play Store library. I don't want to remove paid apps because I obviously paid for them so that means that they are useful to me in some way or another. However, I have accumulated a list of around 500 apps, of which 90% aren't used anymore.
The problem is, I can't remember which apps I paid for and which not. When I click on each app, I sometimes don't see that I purchased them, just the standard "Install" button.
Is there a way to filter out paid apps from my library?
