Re there any note taking apps that require a password to open the folder? I am a teacher and have a classroom set of iPads that I want my students to use for almost everything, but obviously can't afford them seeing work from a previous class. Any suggestions in general for this (maybe how to have multiple accounts)? I have emailed the developer of Notetaker and he had said it was worth looking into but I have not heard back from him in a couple of months now. Any help would be appreciated.
