Metaphysical App

A Metaphysical App is a smartphone app that has a supernatural function. They're usually found in Urban Fantasy, where they can be a major part of the plot or just another aspect of the setting. The most common form of such an app is a magic product being applied through technology. The more rare form is an advanced form of technology that resembles magic.

Whether those apps are Magic From Technology or the newest version of Magitek may vary according to the setting. Be careful that a Technopath doesn't put their hand on a phone that contains one of these.
