We do use the "YouVersion" Bible app as a source for the bible text. this offers us more flexibility with translations to offer.  if you load the Bible app from YouVersion to your device it will allow you download the the version you choose to your device. this makes it available off line (see instructions below).  This along with, the fact that our Quiet Time app loads content one week ahead will allow you to use all the features of the Online Quiet Time on or off line.

here is instructions from their help center on how to do this.
