The free version is not very usable because you cant create custom tasks. But it gives you just enough of a taste to see if you will like it. I hate spending money on apps but I love this one so much that I am considering buying the full version. Not only is it well organized and easy to use, its pretty to look at. If you care more about functionality and less about looks, try Chore Checklist which is a free app.
