Looks good but I think it can be better. In the My Yard section, you have the opportunity to really help educate the user on topics like Root Depth, Allowed Depletion, Efficiency, and Available Water. This will help tie all the pieces together and create a greater understanding of what really goes on in the lawn.
I know there is a link that you all refer too and I've read it. I'm planning on determining the root depth for each zone to get a picture of my base, then do a water audit to understand the efficiency (or lack of) of the sprinkler system. It would have been helpful if that guidance was provide by the app or webpage app and not by stumbling across it in a post.
My 2 cents worth.
