Are you getting frustrated at not being able to lock your iPads in the library database app? The good news is that the iPad and iPhone have a feature called Guided Access. I use this feature myself when I hand my iPad or iPhone to my 2-year-old.
That way he can’t leave the program and start moving my icons, start checking off my to-do items or replying to an SMS.
It's a simple setup, and I have created a short video to show you how to do it.
