The site supports BeerXML import. There is a free trial that allows up to 5 recipes.
Recipes link to the yeast starter calculator and the advanced water chemistry calculator - with auto filled values from the recipe. I find it easy to get the right amount of yeast on brew day and ensure my mash pH is where I want it.
If you are into record keeping the Brew feature is handy. It does actual ABV, efficiency, attenuation, mash tracking, etc. It can even build a report so you know how much 2-row, or Cascade hops you used over a given time period. I used a lot of Amarillo last year!
The site also includes a shopping list, inventory, water profiles, label generator.... I could rattle on...
Hope you enjoy it, and do let us know if you have any questions. Our mission is to help you brew better beer!
