The key is to recommend the products you are advertising. Don't hide away the ads like they are something of which to be ashamed. Find a product or brand you like, and honestly recommend them. Have a header that says "Products we admire" and display products that hopefully relate closely to your demographic, if not your app. You can't do this with Google PPC display ads. They will shut down your account because you're not allowed to encourage users to click on PPC ads. But you can do this with affiliate ads.
