An app for ghostbusting? There actually is an app for detecting ghosts, believe it or not.
This decal for your iPhone goes further, though, and turns your entire phone into a ghost collection and containment system. Fine, yeah, okay… so it’s just a decal but would your average ghost want to take the risk? They’ll see the unit and keep away.
Where do you buy such a handy decal? That’s right: Etsy.
