In other brewing software I've used I could set a target OG and then add fermentables in percentages of the total grist and it would calculate the required weight of each one. Are there plans to add this functionality to Beersmith Mobile?
It is on the desktop version (click "Grain Pct" button on the design page near the add- ingredient buttons.) I have it on my list to add to the mobile but have not implemented it there yet.
