Geocaching is one of the best justifications for handing a kid a smartphone. Instead of pulling their focus downward into a simulated feed, the app uses the device as a navigational instrument pointed at the physical world.
You check the coordinates, pocket the phone, and start scanning tree hollows, drainage pipes, and magnetic fake bolts. It turns an otherwise boring family hike into an active mission where kids willingly walk three miles without a whimper.
