Metaphysical App

Since the introduction of smartphones in society, phone apps have become a part of our modern lives. They each have different uses like taking a picture, streaming a video, or taking care of finances. These examples are ordinary uses, but what about a more fantastic application. A Metaphysical App is a smartphone app that has a supernatural function that can affect a person or the world. They're usually found in Urban Fantasy, where they can be a major part of the plot or just another aspect of the setting.

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.
