So, a few months ago I downloaded an android app for free from a website. The app initially costed money but I got it for free from the site. And I installed it to my phone, then I tried to run it, I had to complete an offer to actually use the app (I only had to fill it out once) Now that I look back at it, I think it's GENIUS!!! If anybody knows how to do that can you please show me how? Thank you!
