App For Tv Remote

[tearinghair]

I noticed that there's an app available on my phone (Samsung galaxy SIII mini)for a TV remote control. Is this a good thing, and could it affect the efficiency of our current remotes?
I ask because OH insists that he needs all three (three!) of the controls; one to switch between TV and satellite, one to change channels without moving up or down one at a time, and one to change the volume. It does seem as though the other functions on each don't work properly; I suspect that they need reprogramming, but I'm not allowed to touch them. (I have tried new batteries). We also have a fourth, new, one which 'doesn't work'..... I would love to be able to have control of the wretched set just once in a while.

Ah...I was too hasty. It's not for TV, is it? Clearly I wanted it to be....
