I use Litchi for most of my flying, but it is not a good option for mapping, particularly since it does not support automatically resuming after a battery change.
There are several apps focused on mapping that would be much better and free as flight controllers without using or paying for the actual processing service. I find myself using the Drone Deploy app most often, primarily because I can preplan missions on the PC. They had some glitches early on, but it is a stable app now and they continue to enhance it.
I have one quarry that I fly every month that has more than 400 feet of elevation changes and use the Map Pilot app from Maps Made Easy with the $10 Terrain Awareness feature there. But it has limitations such as having to plan on the iPad, no simple way to move a mission from one iPad to another, and no support for complex polygons which makes me fly more area than required. Most frustrating is the requirement to have Internet connectivity to download the terrain data with EVERY battery change. So I end up having to hike up a rock pile to get enough cell signal to slowly download the data, losing minutes of flight time on each battery.
