Altitude control above the mountains

Hi guys, I’m posting an old topic in the correct section, I apologize again for my forgetfulness as in the previous post; the topic was, always on my past use of the FORE FLIGHT software, speaking of VFR, during the planning of the reporting points, it indicated the correct altitude to keep by showing me the heights of the various mountains, by clicking on the altitude page even in flight, it showed me the distance between the plane and a mountain, if for example there was a change of route, I immediately saw if I had to change the flight level if I climbed higher or deviated, this was the request thanks.
