This app requires you to download mediatap which is a companion app that you need in order for this to work. Only problem is, that the website to download mediatap (their official website) is down. And doesnt look like it will be back soon (their domain expired, and I dont think that would happen to a company that plans to continue). Without media tap this renders the app USELESS. What a waste of $6 bucks.
