Can I get total vertical ascent in a track?

Yes. While recording a track in portrait mode, vertically scroll the bottom part of the Track Recorder page to view an altitude profile; scroll further to see current elevation, gradient, and total ascent/descent.

While in landscape mode, current elevation, gradient and total ascent/descent are on the main view of the Track Recorder. To see a graphical view, touch the blue graph button at the top right of the screen.

Your current altitude is always available on the Position page. You can get a summary of the track, including the altitude of the highest and lowest points, when using the Email feature. Your track also contains altitude data which can be viewed in Google Earth.
