Can I view iPhone apps on my tv?

I downloaded a sign language app to help me learn it but I'm finding it a bit difficult on my iPhone, I know there are cables you can buy to plug your phone into the tv to watch movies etc i was wondering if this would work for the app?
The app is full if videos, if I had one of the cable could I view the app on my tv?

You can find cables that can connect you iPhone to your TV, but it would only work with the videos.

I think with the apple tv box you can.
