After I had carefully checked the compatibility on their web site I downloaded it from iTunes. After starting the app on my iPhone 4S with latest iOS it immediately found the source (AVC-A1HD) in my wireless network and configured it. Took less than 5 seconds. And it works flawlessly. Showing all the detailed preferences in the depth of my trusted receiver conveniently on my phone, better than the remote actually.... :-) The Denon Remote could never find it in the network… Recommended!
