Terrible app!! Downloaded 1.3 gb of data on LTE costing me $$$ in overage fees

I was using the app to find a station. Noticed some flickering images in app but thought nothing more of it. Left app on for about 5-10 mins and shut it off. Then I got data alerts from my cell company saying Im over my 3 gb plan!!!!! Now Ive really gotta pay because of this app!
