Toodleddo, an online to-do list

Toodleddo

An online to-do list to stay organized, motivated, & more productive. Among the
features are -

Organize Your Tasks

Use folders, subtasks, due-dates, priorities, tags, contexts, goals, notes, time
estimates and other information to easily organize, search and sort through your
tasks.

Improve Your Productivity

Having a single place where all your to-dos are permanently stored and easily
accessible will allow you to relax, knowing that you won't forget anything.
Hotlist, email and sms reminders, too

If you are a procastinator, Toodledo has a special tool that analyzes dates,
priorities, and time estimates, to create a customized schedule of the best use
of your time.

Go Anywhere

Always have your todo list at hand. You can get Toodledo on your mobile phone,
in your email, on your calendar, in your RSS reader, via IM, and integrated
directly into your web browser. You can even print up a special foldable booklet
that will fit in your pocket.

Collaborate

Easily work with other people on shared projects with Toodledo's collaboration
tools. A permission system allows you to set exactly who has the ability to
read, add and edit your tasks.

Customize

Everybody is different, and everybody has their own way of managing their tasks.
This is why Toodledo can easily be customized to suit your needs. If you don't
see the functionality that you want, let us know and we will add it.

Import Your Existing Tasks

If you already use a task manager, you won't want to type in your tasks all over
again. Toodledo can import tasks from many sources, including your Palm OS PDA,
Microsoft Outlook, Apple's iCal, and other online todo lists.

Web 2.0 Buzzword Compliant

We use all the fancy technologies (XML, RSS, AJAX, REST API...) that people have
come to expect with innovative websites.
