Unfortunately, no longer working
I have had this app for years, just started brewing again, and the app no longer functions. It was a great app contributed by Jamil, when there were few alternatives to doing it by hand. Fortunately, there are lots of other tools now available. I would recommend Brewfather which has a broad home brew capability, including yeast starter calculations.
What a piece of rubbish. This app tells you nothing and is a total waste of money. Do not buy!
Save your money
This app does not give the same options or calculations that the website give.
Waste of $
Don't waste your money! Free calculators do more than this worthless app.
Read the reviews, or shall I say lack their of before you even consider purchasing this application! It seriously serves no purpose!
