For the geeky aviation enthusiast to track and view planes flying in the local area as well as around the world using a radar style similar to the radar screens that Heathrow air traffic controllers use in the real world.

This App is a 'viewer' to any Virtual Radar Server you point at on the internet serving live flight data and it defaults initially to www.adsbexchange.com. It can be changed using the [Server] menu.

You can also filter plane data so that you will see only planes that fit a given filter criteria using the various flight parameters and variables available here: http://www.virtualradarserver.co.uk/Documentation/Formats/AircraftList.aspx

Built-in ADSB receiver/Dump1090 server listener functionality so with the correct hardware connected to your mobile device you can receive live plane data in your area directly from the air.

Real time GPS feature which allows users to leverage their GPS receiver on their device to provide real time speed direction and altitude of their present movements.

Proximity Alert feature depending on distance and height away from aircraft to your current GPS position provides a visual and audible warning "traffic traffic".

Simple 3D View mode with yellow or white planes.
****For full livery coloured planes see full version on the Playstore*****

3D with VR - using an Android device that has the correct sensors (namely gyro gravity and compass) you will be able to move your phone around in a full 360 degree circle in the real world and see where planes are positioned around you.
