Track analysis mode
This mode provides you a way to look over a track you have recorded or downloaded to the phone; first, you choose the track, and then it is drawn on the map.
In the frame in the topmost part of the screen, you can choose certain part of the track by sweeping your fingers over track altitude chart.
You initialize this mode by choosing a track from the menu. Because there will eventually be many tracks to choose from, they are organized by months.
