Great app, now wheres the iPhone 5 update?

Ive used binaural beats technology for 20 years and this app has pretty much replaced my expensive standalone machines. I am however very disappointed to see that the last update was in 2010. Im only giving the app 4 instead of 5 stats because Id like to see the interface updated to meet iphone 5 standards. (Some new features and/or programs wouldnt hurt either!).
