Pitch your yeast like the pro's do with this easy to use calculator that supports dry yeast, liquid yeast, slurry, and starters. Calculates liquid yeast viability based on manufactured date. You get to choose your desired pitch rate in million cells / milliliter of wort / degree plato. Also calculates how big of a starter to make and how much DME to add to that starter. Up to three step-ups are supported, so you can even start from a yeast slant! Two different growth curves are supported. The first comes from recently published research at Braukaiser, and the second from a study by Chris White.

Poor Navigation Between Screens

This app has poor navigation and UI to transition between screens. Went to the starter to adjust and determine if it was enough for my batch and the numerical pad would not recede and I could not go back to the original page. Regrettable purchase and WAY overpriced for what you can simply google and get from Northern Brewer or any other website. Do not buy.

No longer working

The pull-down tabs no longer work. I deleted and reloaded the app several times and no change. It work great up until recently

Exactly what I was looking for!

This app blows the Mr. Malty away. I needed a more in depth calculator for a 10 gallon batch of beer. I needed a calculator that helped calculate yeast growth through several steps to achieve a certain pitch rate. This allowed me to do that.
