Landing pads and good "safe" landing locations are not going to always be there. I do a lot of waterfall droning and hand catching it is about all there is - as well as hand launching. Only time I have lightly clipped a finger was in some winds and the drone (
Air2) was moving a tad bit. Had on some gloves at the time, so no damage. Usually fly with a couple other droners, so one will catch while the pilot is landing.
Never have used the "app" to land in hand. Downstick on the controller does it all. Hard to pay attention to the drone and the app at the same time, while the controller stick is pretty simple and you're using it anyway typically to land. RTH is a failsafe for me and I do not use it 99% of the time, as RTH may not be close to where I am depending on GPS signals and such in my location.
