Updated - home button issue fixed.

Cant comment on accuracy, yet. But it only works from the first launch. If you go back to the springboard and run another app then try to launch db, it wont measure sound even after hitting start/stop. The only way to get it working again is to double tap home, kill the app, then relaunch it. Running a iPhone 5 with latest iOS.

Update: 5 stars for being so responsive to fixing the home button bug. Wow. Thank you, developer for responding to feedback
