There are lots of awesome, simple web tools for your task lists, but Daily Todo focuses on helping you manage the items in your day-to-day routine.
Daily Todo is ridiculously simple to use. You don't have to create an account to start, you just click the big green button on the home page. From there you enter every task you want to accomplish on a daily basis in a text box, separating them by each line. When you're done, click the Save Tasks button and you can start checking things off (represented by a green dot). You can always add new tasks or remove existing ones, but that's pretty much where the features end. Daily Todo is a nice, handy task-management tool, thanks to its simplicity and ease of use.
