how to make money from app ??

i saw there is a lot now, but i wonder how they really make money other from AD (my country ad pay is very low)......

I think you have to select alternative way.
You should select what type of work can be done well in your country.

 

You can try developing a free and then pro (paid) version of an app. It's another way to monetize Droid/Iphone applications.

 

you can sell your product through app.
