Aside from solving the altitude/elevation discrepancy between altitude measured by your iPhone, to your elevation above sea level, this app also converts your altitude to the correct elevation relative to the sea level to give you an accurate measure of your elevation. This app also provides you with access to the USGS elevation web service. This app's internally generated elevation converges with that of the USGS value. Some of the great features of the Elevation for Real iPhone app include: real-time map with pin-annotation of your location, English or Metric units based on your region setting, start/stop button, and one touch screenshots.

Yet another decent iPhone app to measure your elevation. Altimeter Deluxe shows elevation using your iPhone's built-in GPS, displayed in a high quality graphic design. The app displays the height in meters or feet, accuracy, longitude, and latitude. It also disables the auto lock feature to ensure that the display backlight is on while the application is running. Some reminders from the app developers while using this app: it only works outdoors, it's more precise when in places with no houses and trees around, and when there are more satellite connections.

Interfacing native location and mapping abilities of the iPhone with the US Geological Survey and Shuttle Radar Topography Mission (SRTM) elevation data, this app calculates your approximate present position and then marks it on a street map. It then displays the corresponding latitude and longitude together with USGS or SRTM elevation. The app also gives you the option to switch between street and aerial photo/street hybrid maps.
