Couldnt hate this app more

$5.79 for an app that is full of ads? An additional $5.79 to upgrade? Silly me, assuming that when I paid a premium price for an app (with plenty of free alternatives) that Id get a premium app. Nope. Looks horrid too, like they havent optimized for retina or the 6 line.
This is the worst purchase I have made on the App Store. How do I get a refund? That would make a better ad in the app.
