I am the author of this app and have one question - did you ever clicked on ads in this app? I am just trying to make a kind of "Survey" between users to know, which way to go. I have the paid version, but it doesn't sell well, so I made the Ad-supported version, listed in Google Play for free, but not many people click the ads.
What do you think? Do you think, that having the app free, supported with ads is viable option for me?
