Displays a photo-realistic aircraft style Airspeed indicator, or Speedometer on your iPhone. Modeled after analog instrumentation in general aviation aircraft. This application is a cool looking dual unit speedometer. The meter movement is smooth and realistic.

See your current speed in both analog and digital displays simultaneously. Both displays can be configured independently to show Knots, Miles/Hour or Kilometers/Hour. 4 different scales. 50, 100, 200 and 400.

A pop-up view displays all information coming from the iPhone GPS, including Latitude, Longitude, Altitude, Speed, and Uncertainty.

Includes a simulation mode that allows the instrument to be demonstrated indoors without a GPS signal.

Has a selectable smoothing effect to give the pointer a realistic movement.

Requires a device with built in GPS and a good GPS signal.
The iPhone GPS has a limited resolution and will update no faster than once a second. Additionally the iPhone GPS reports values that may be a few seconds delayed. It may take a minute or two for the iPhone GPS to "lock" and provide accurate values.
You must be moving at a fast walking speed or better for the iPhone GPS to report a speed.
A good GPS signal can usually be achieved with a clear view of the sky.
This software has been tested with iOS version 4.2.1 through 5

Continued use of GPS running in the background can dramatically decrease battery life.
