Web/iOS/Android: Plane Finder delivers next-level flight tracking in real time. You open the app to a world map of 12,000+ planes moving in real time, complete with a search feature, so you can see where the flight you're tracking is at at any moment.
You can use the map to find out useful information, like the congestion of traffic at the landing strip so you know whether your passenger will be available for pick up quickly or not.
Plane Finder also has an augmented reality setting so you can take a photo of the sky from your phone and see which flights are above you, which can also help when guessing how long you'll be waiting to pick up a passenger after arrival.
If you're using the mobile app, Plane Finder can also send you a push notifications when a plane is near or has arrived, so you no longer have to watch the clock and Google -- the information is delivered right to you instead. Check it out at the link below.
