With AltitudeProfiler you can create altitude profiles beginning at your position through the direction of the phone or profiles for concentric radiuses in a compass-view. You can also create a diagramm of the relative time to walk the selected distance for each direction. An other option is to estimate the slope or climb..seehttp://androgeoid.com/2011/03/graphic-local-elevation-displays-with-altitudeprofiler/for a test
