Paid for a product that doesnt work AT ALL!

Id rate it zero stars if possible. I paid the $1.99 to use on my iPhone6 and not a single thing on the app works. I can scroll through the options but I am unable to select anything other then what was preselected when I opened the app. Ive tried deleting and downloading it again yet nothing new. Whats the point in charging people for a product that doesnt work AT ALL. Wish I never wasted my time or money. I want the refund just on principle alone. It should be free this way no harm no foul when people dont get anything out of it.
