I'm heavily committed to Mem-Map and my iPhone but anyway I don't know
of an iOS GPS app that records altimeter-based altitudes as well as
x,y positions. Nor one that reports gross asc/desc for a track, which
would be a useful supplementary estimate.
Locus Map does all this, albeit only on Android. It can even
fill in the altitudes after the fact, using the SRTM (Shuttle
Radar Topography Mission, http://jpl.nasa.gov/srtm/
) data, if
you put that on the phone. I have done exactly this to try it.
The app shows you altitude/distance graphs for a track and
separates ascendence and descendence data.
I'm pretty sure there is no iOS version though.
