I use Excel for Pot Volumes and Notes for reminding me what hops I want to buy, but haven't seen anything else out there. Tucows or somewhere like that would be the place to start looking.
I came across this web site a long time ago. I think the software was in development when I last looked, and the forum/download link does not seem to work, but the screen shots looked good for brewing.
i usually save my current beersmith recipe into a word doc and use that on my smart phone to ponder over while on the bus etc, i also save the brewsheet for brewday so that i can use my phone instead of the usual printout. I think i'll just stick with that until my software (beersmith) is smartphone ready... would definately be keen for that.
