Good job, I am working on a similar tool. There are lots of free great recipe managers on the web. What is the main differentiating factor that makes this worth 10 a month?
The important thing that differentiates this is that it is solely a replacement for a recipe box or other strategy for storing recipes. Most other recipe managers are tacking added on to recipe discovery tools. 7courses allows for sharing recipes, but is 100% focused on making it dead simple to manage your recipes.
And we have a kick ass mobile web app.
