A free program for Android, by V Vorld.
This app is designed for those who are interested in knowing the exact speed of their flight and the altitude at which their plane is flying.
This app uses the built-in GPS sensor of your phone to get the exact speed and altitude of the airplane. The speed is displayed in kilometers per hour (KPH) or meters per second (MPH). The altitude is displayed in meters above sea level.
The app also displays information like current speed, time, altitude, and distance. It is designed for use in a fixed position and will not move or be affected by the device's motion.
