As of September, 2014, Audio Xciter now crashes on a new iPhone 5S with iOS 8.0.2. Repeated attempts to get support to respond (from their website and directly to email) go unanswered.
This is the only app that has crashed on my iPhone in years. Restarts, redownloading, zeroing the phone and reinstalling and still this app crashes.
