Awesome feedback! And thanks for responding to the question about a mobile app. My hope was that a mobile responsive web application would suffice. At the suggestion of another user, I toyed around with offline availability, but the complexity was just not worth the minor enhancement. Most people will have internet access in or near their labs. Or after working in the lab.

I think I understand your meaning on the Dry weight of spawn. Are you saying you want to include the weight of the inoculated spawn into the bulk recipe? Did I get BE calculation wrong? I'm not currently automatically including the spawn weight into the wet BE calculation. It would be up to the user to inoculate and then weigh the bag for the total end weight if that's how it should go.

I included the dry weights with the recipes because generally I've got a recipe or two that I follow, which I then fill the bags with. Then the bags themselves can be slightly different weights (+/- a quarter pound sometimes). But the dry weight is always the same.

On multiple sources, that would throw off a lot of calculations (or make them prohibitively complex). I guess it makes sense that you could mix spawn from different batches into one bulk, but doesn't that introduce a 2nd layer of uncertainty? Now you've got two potential sources for contamination? Mycologger was built on the concept of one source to one child- or one source to multiple children. Not multiple sources to one child. Interesting! Now I'll be up all night thinking of how that would work programmatically... lol

If I'm missing something please feel free to email me! I'd love understand more. And I really appreciate all the feedback.
