The thing I've found so far with the Stitcher's Helper is I can put it in my droid and have it with me always.
So when I go to the LQS, Joanns, Hobby Lobby and such. It also has several calculators for different blocks.
It's also got a project list and you can (not that you would want to) keep up with how much you're spending on a project.
Organize Quilters is different than the other one I was talking about. Organized Expressions was what I was referring too.
