I started with Beer Tools, now I'm transitioning to beersmith. I print recipes from both. I have a brew day log that I made up. Section for starter, and then the steps with gravity readings, ph, amount of water for strike and Sparge. Then I also have a fermentation log. My recipes are stored on Dropbox as a native Beertools file and also as a PDF that I can access anywhere.
I like Beersmith for the ease of access with Beersmith app on ipad or phone.
So each brewday has about 3 pages.
It's fun to look back on the history of your own brewing.
