I was developing some apps. Now i'm thinking to upload on Google Play for free. My app is designed for offline use. I'm not clear about that they pay per install after user install my app from anywhere or play store. Is Pay Per Install is best options for my app? How do you think? Pls leave your idea. Is there any Ads service for my need? I have read that Admob is not much for offline app. They business work as a CPC. Do you have any idea about leadbolt?
They all require internet connection.
So it sounds like your app is not a good fit for in-app advertising.
