Altimeter X 3.0 uses your device's sensors (GPS, barometer) and an elevation database to track your altitude as accurately as possible.

iOS/GPS altitude
Altitude estimated by the device's location service. It works reasonably well in most situations but can't track small changes and can be unreliable indoor.

Barometric altitude (iPhone 6 minimum)
Altitude based on the device's barometer. This is how most hardware altimeters work. It can track very small relative variations but must be calibrated with weather data or GPS. Calibration with weather data grabs current sea-level pressure and temperature at your location from a nearby weather station. GPS calibration takes the current iOS/GPS altitude as a starting point then uses the barometer to track changes.

Elevation database
This method displays earth surface elevation at your location by polling an elevation database. It works even with very imprecise location data but requires network access. Surface elevation usually includes buildings and trees.

What’s New

Needs better description

This app should really be promoted as a tool for flying. At least they should let users know there isn't a great deal of accuracy. If you need something that had less than 10' range of error, than this app is not for you.

Simple, fun

The app provides a quick and simple way to get your altitude. I have never had a chance to check the info against an authoritative source, but the results that I get using the program seem to jive with the other info I have. My only gripe -- a small, small thing -- is that I have yet to see a way to set the app to report in feet, rather than meters, as soon as I open the app.
