Is there an application where I can lock the mobile phone application?

cellphone application

When I study for the exam, I want to lock it so that I don't use it at all except for a few essential apps. I want to lock the Internet at all. Is there an application that allows me to lock it like this?

There's an app called, "How much do you use?" I think that's exactly what you want.
