Here's a link to a form the ND Dept. of Agriculture has for spray records. I would like an App to fill in a form like this on my iPad. I can make a form in Numbers to do most everything on the form except for drawing in the area that you've made an application to, but it would be nice to have an App that had drop-down boxes for the chemicals and populate the EPA # fields, REI, & PPE. If your App could do this, it would have soem value to me. Most of the other things you show that it can do would be sweet to have with, but would be double entry along with my desktop software.
