Features: - displays the height in meters or feet - displays the accuracy - displays the longitude - displays the latitude - disables the autolock feature (keeps the display backlight on while the application is running) Please note: Altimeter Deluxe works only outdoors, as it needs a connection to GPS satellites. For best precision choose a place with no houses and trees around, to have a clear sky view. The precision increases if more satellite connections are found, this can take up to a minute. The "Location Services" option in the Settings has to be activated. Works on iPhone 3G and iPhone 3GS. Does not work on iPod touch. Follow us on twitter: http://twitter.com/PlanetBlueArt
