Heard of an app called AppNana? It's an app that rewards you for installing games, testing apps, watching adds, with Google Play, Amazon, and iTunes gift cards, and more! And the app, is completely free!
An easy way of earning Nanas is to add other people's Invite Codes. Whenever you invite someone or get invited, you get 2.5k nanas!
My code is t3305123, pm me your codes so we can just keep gettin nanas for doing pretty much nothing at all!
