There is an app in the Google Play store I would like to purchase that is not available elsewhere. Ethics and morals guide me in my decision not to give any money to Google. Similarly, I don't pirate software. Can anyone recommend a legitimate app to earn a small amount of Google Play store credit so I can purchase this app?
The app you recommend can run on any platform (it doesn't have to be an Android app) and can even be a web-app. All I ask is that it is legitimate, and not some sort of scam. Oh, I also ask that it doesn't have any intrusive permissions.
I did try Google Opinion Rewards, but I didn't receive any opinion surveys, likely because I don't share GPS data with Google.
