It's easy of use since all information can be entered directly from your iPad or Android phone without needing any external device like PC/laptop! And it works perfectly in conjunction with my DJI Phantom 3 autopilot system giving me control over everything about its flight path while recording videos at each point along this journey using DroneDeploy service as well (for which I paid extra).
The only thing missing here would have been some kind off "pinch zoom" feature where we could pinch out our way into details instead just going straight there by tapping those places one-byone manually - but maybe someday someone will do so :) In terms what problems does solution solve? Mainly logging flights & keeping safety records up until now has always taken tons time doing manual work via paper logs etc., even then they are not accurate enough nor secure either due their potential leaking if lost accidentally somewhere else than secured place (iPad), hence having such tool.
