---IF YOU WANT A FULL FEATURED GPS APP, PLEASE TAKE A LOOK AT myCoordinates Pro---
myCoordinates is a free simple app to tell you your Latitude, Longitude and Altitude (in both Meters and Feet), GPS Speed, and Heading where available.
All are fairly accurate and use the iPhone's built in GPS receiver to get the coordinates.
The coordinates are fairly accurate, normally within 25 meters, so this app is not designed for critical purposes, however is ideal for casual users.
The Location Provided by this app IS ONLY AS ACCURATE AS YOUR iPhone's GPS.
myCoordinates Lite will run in the background on supported devices, however please note:
Continued use of GPS running in the background can dramatically decrease battery life. Background GPS use can be enabled/disabled in the settings page of the app, and this can help to improve battery life.
