Some questions about applications for android. I was wondering what kind of application you use/download. (prefer) Do you like buying them because you don't like ads or you don't care that there are ads ? What is better ? Is it better when the application has notifications or banner and is free? How much you can pay for an application that has no ads ? (no matter what kind of applcation) Do you buy applications often? Feel free to say few words about it.
