Anybody have a favorite app for mapping and crop survey?

I've tried DroneDeploy and was impressed.
AgisSoft Photoscan is not an app but is also very good

Litchi for IOS, Drone Deploy, Map Pilot is awesome as well

I use MapPilot, Go and Litchi for capture
and MapsMadeEasy for processing

I use maps made easy for data collection.... Then process with agi photo scan... I have been impressed with drone deploy and pix 4D but the monthly subscription for those 2 means it will have to be very busy for me to pay that monthly bill... It has the advantages of processing multiple jobs at once.

Pix4D seems to be a nice software for the maps
