Zee is an employee for the company that distributes the Retrospec app. It is a fussy thing, and I'm not nearly savvy enough to be able to say that you *can't* delete it, but chances are that it's best that you don't. There are good pieces of advice to find, here. Those who have the app are aware of things that go weird in the city, and around it, too. Those who don't have it, on the other hand, will have a lot of trouble believing you that it exists.
