You could always try my Brew Chart/Workbook (below in my signature). Gives you pretty much what a program like Beersmith would give you, but it's free. It is setup for batch sparge all grain brewing and covers pretty much everything you'll need from recipe design to first taste.
Any questions just ask.
Here is what the first tab looks like where you would design a beer or input a recipe to brew. As you scroll over each particular ingredient a description of it pops up with a profile and best use. There is no math for you to worry about, all of it is taken care of for you within the workbook. There are many other tabs dedicated to your brewday, water profile, yeast pitch, bottling/kegging, etc... as well.
