Everyone has a different way to record what and how they brew, it's the only way you can both be consistent, and get better at what you do. Initially, I started out trying different brewing apps and software like the majority of people out there in homebrew land, but it left me feeling underwhelmed, and uniformed.
Then I saw a tweet by matthew clark (@thornbridgematt) that said "Homebrewers! Ditch those brew calculators and learn to work it out by hand. http://tiny.tw/38L9 "
