I only use the Litchi for Waypoint missions, since they can be pre-programmed on my pc, without having to try them out and create them as you fly.
You should also use the google altitude app though to evaluate the mission altitudes before you fly; you do not want to set the wrong altitude. Remember, the altitudes set are all referenced to the Home Point Altitude.
I think many of the limitations mentioned above, like max altitude, are not the app's limitation, but those are set by the craft.
I usually start initially with compass calibration, camera settings, check GPS and do an initial quick manual flight using the DJI Go app. to make sure everything is fine before a long waypoint mission. I can do that using the Litchi app, but I tend to use the DJI Go. I then shut the app off on my iphone, (2 quick taps, and move it off the screen) and start Litchi. I do not have to turn off my iphone. I have flown about 3.5 miles out so far without losing RC connection, but I know even if I do lose signal, the mission will continue on. I was told by Litchi (I have not tried this, nor I have confirmed this) that if the P4 distance exceeds the current battery life, then the firmware will automatically start RTH. They do not control this feature. So be careful with RTH altitude setting, before each Litchi mission.
ALso, make sure you use the app at home if you fly areas where there is no internet connection, like I found out the hard way. I planned a mission on my pc, then I went out to find out I had no map service. GPS still worked, but I prefer to see the map and follow the mission on the map. I had to cache the map at home using an active connection, then Litchi remembers, even if there is no internet connection in the area you are flying.
