<p>Hi,<br>
Yours looks like a very good application, thank you!<br>
You are fortunate, because my phone got hung too.<br>
My phone is an iPhone 4 (not "s") 32GB, IOS 7.1.2 (11D257), hardware model 3,1. I installed the app, made a quick test and seemed to work ok. Then I tried to activate the voice control, the phone showed a black microphone figure and "Starting up..." message... and the app froze, just the app not the phone. I was not able to un-froze the app. Maybe I didn't try hard enough...<br>
I shot down the phone, then turned it on and restarted the app. The app started on the same screen as before, still showing "Starting up..." and the black mic, after a second, without any other action, the mic turned green and the screen showed the words "OK" "NEXT" etc. When I spoke the words they were recognized swiftly. The app seems to work ok now.<br>
I looked into the Diagnostics and Use log, but cannot identify any crash entry related to your app.<br>
I hope this helps.<br>
