1. lock my iPad on time

(I found some features that Apple suggested. for example, guided access. but I don't know that In my app, Can I control this function? or I need other ways to lock my iPad on time.)

2. Application that cannot be turned off
Can I develop application that cannot be turned off in without developer's permission?

I need an iPad manager application that can control the usage of the iPad.
