I've created my first app and I'm ready to release it to google market.
however I want the chance to make some money out of it and so I want to add ads to it. (my app is free)
thing is I have no idea how many people will download my app.. can be 10... or it can be a hit..
so far from what I've read everybody suggest to use admob or something similar, but they all cost money.. and I've read some negative feedbacks about them..
I want to make money out of my app not lose it, so, is there a way to add ads that won't cost me a thing? and there's a chance to make some money from it?
