Just a quick post in my continuing series of free (or cheap) and useful services for your one-person home office. 

Ta-da Lists, by 37signals, is a 100% free list service.  If you can list it, you can put it on Ta-da Lists: to-do items, shopping lists, things to pack, etc. It’s very simple to use, which is one of my primary concerns with software like this.  I’m not talking rocket science here – I just want to make a list! 

Some screen shots after the jump.

First, the overview screen.  The bigger the dot in front of the list, the more uncompleted items you have. Nice.

Here’s what an individual list looks like. 

To be completely honest, I stopped using Ta-sa Lists a while back, because I started keeping my to-do lists in another application.  But a new feature brought me back: Ta-da Lists for the iPhone.  I LOVE keeping my shopping lists all in one place. 

Here’s the iPhone list in action:

Nice. And free.  Which is nice.
