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

Version 3.0

Version 3.0 is a complete overhaul that adds the ability to use the barometer to track your altitude (iPhone 6 minimum).

Cela ne sert à rien
Même pas possible de choisir les pieds ou les mètres

Developer Response ,

L’application se base par défaut sur les réglages de votre iPhone. Depuis la version 3.0, il est possible de forcer l’affichage en pieds (icône roue crantée). J’espère que ce changement et d’autres améliorations vous donneront satisfaction.

Le top

La version 3 est un bond en avant. En mode baromètre, je peux même voir varier l’altitude en levant le bras. Vivement Conseillée !

Only meters and NO FEET.


Developer Response ,

The app uses the preferences set on your iPhone globally. So if your region uses meters, Altimeter X uses this unit. Since version 3.0, you can bypass this setting in the app (gear icon). Check it out.
