A couple users have noticed crashes when running VerseWise (which is currently an iPhone/iPod app) on an iPad. I unfortunately introduced this problem while adding code for the upcoming iPad release.
The problem occurs when VerseWise tries to rotate. One quick fix is to go into Settings and turn Autorotate "off". Or you can just try to be careful and not rotate your iPad while running the app. :)
Of course I will release a fix for this in the next update. I hope to also include some new reading plans.
