Plane Catcher

Point your camera at a plane in the sky to see its flight number, airline and route.

Needs camera, location and motion access. Works best outdoors, away from metal and magnets.

Calibrate

Put a plane you can actually see in the centre of the crosshair, then tap it below. Phone compasses are often 5–20° off; this fixes it.
