Currently you do need a free cloud account to do this. Go to BeerSmithRecipes.com and create an account, then verify your email address.
Once this is done you can open your BeerSmith desktop (Make sure you have version 2.1 or higher) and log into your cloud folder (View->Cloud).
The final step is to simply copy/paste the recipes from your My Recipes folder to your Cloud folder. Once you do this they will be stored on the BeerSmithRecipes server and if you log into your cloud folder on your phone you can view, copy, save or run the brewday timer on them there.
Once you have your account set up it becomes very easy to move things back and forth by just copying them to your cloud folder and deleting if no longer needed there.
