It is always great to see new apps - and your looks very nice.
Though, $25 will be a tough sell around here. I could only see spending $25 if the app controlled (without me programming it) ALL my HA/HT (XBMC, Vera, EventGhost, Windows Media Center, JR Media Center, Sickbeard, SABnzbd, etc) in a single shot and did it as well as the individual free apps do... this is highly unlikely to happen.
Right now, I have a collection of very good, very free (no ads), apps that do all of these, separately... which is fine, since it takes only 2 seconds to launch any of them.
I wish you the best with your app.
