Delete free apps from Play Store library 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?
I suggest you use both a PC and your mobile for this solution. 

Using your PC, visit your Play Store's order history. It would list only those apps you have bought so far. Now, in your Play Store app, go to Account (rightwards swipe from the left edge) &rarr; Library.

Compare the two lists. The ones which would not match would be the free ones. 

This is not user-friendly but should get the job done nonetheless.
