Had to uninstall iPad app today, as it won't launch. 
Yesterday during a talk to a church ladies group the app froze and I had to turn off the app in mid-presentation. Not good for the nerves (or Logos reputation with those ladies). 
I'm not going to reinstall until I hear that the app is working properly. I'll just use another Bible app that I have had since my old Palm-PDA days.
EDIT I am still using iOS 5, since iOS6 doesn't work on my old iPad.
