In my iPad settings there is an app called null what is it? When I go to settings on my iPad it shows an app called null what is this? What do I do about it? Is it bad or nothing to worry about?
It's not obvious where this app came from. According to the answer to this question, it probably is an app that was incompletely synced with iTunes.

There's nothing to worry about, and you don't need to do anything about it.
