In-app purchases will give you the desired revenue. It means you need to invent some addons to your app that people may buy to use, imagine, in order to upgrade to better functionality or something similar.

Yeah. In app purchases are the common form of revenue. As well as putting ads into the game.

Microtransactions are a popular way to cash in on your game. Also you can make it closely connected with a website, meaning users have to use your website from time to time to register an account or something like that and you can have ads on the site instead of in the app itself.
