I dont believe they did an Android app for this only i-stuff - Denon website confirms this
Your title mistype is a very accurate if you have ever used any of Denon's control apps - they are rubbish and will have you throwing your tablet out the window in frustration so you are better off without them - trust me your sanity will thank you.
They do an android one for the 730 - but the reviews are terrible and only gets a 2 star rating, they are being kind but there is no way of putting a minus rating. It is supposed to work with my N9 but it crashes constantly
