Plane Finder

Plane Finder helps you identify any aircraft overhead and lets you know where they're going. It's all clearly presented on a map and you can see pictures of the aircraft you're viewing.

It's particularly useful when you're waiting for a flight to arrive.

The app also has a an AR function that identifies anything in view on your camera. There's a desktop version of the app as well that you can take a look at right now:
