This app is only available on the App Store for iOS devices.


New app to calculate stepped starters coming in sprint 2015.

This is a licensed iPhone implementation of the Mr. Malty Pitching Rate Calculator. It can calculate starter sizes, amount of yeast required, the effect of stir plates, dry yeast rates, yeast viability,and lots more. It uses the same proprietary formulas as the calculator on

Jamil's Books:

* Yeast: The Practical Guide to Beer Fermentation:
* Brewing Classic Styles: 80 Winning Recipes Anyone Can Brew:

What's New in Version 6.5.0

* fix for hectoliters(there are 100,000ml in a hectoliter, not 1,000,000 as previously being used in the incorrect unit converter)

Customer Reviews

Not Worth the $2.99.

Save your $. There are better yeast calculator apps available that allow multiple starters to get you where you need to be, especially for big beers. Checkout Yeast Pitch. Great app and worth the price.

Save your money

This app does not give the same options or calculations that the website give.


Read the reviews, or shall I say lack their of before you even consider purchasing this application! It seriously serves no purpose!
