APP QUESTION

It’s a way to hack a phone to bypass Activation Lock (it doesn’t actually work, but lots of hacks don’t). It should not be on your phone; if it is, your phone is probably jailbroken.

You need to restore your phone to factory settings and not restore a backup→Restore your iPhone, iPad, or iPod to factory settings - Apple Support

Better yet, an DFU restore is a better choice→How To Put An iPhone In DFU Mode, The Apple Way
