I’ve used a lot of tools to keep track of my tasks, but none have been a perfect match for my needs.
Todoist.com was the answer to my prays. It’s very easy in use and got some nice plug-ins, among them one to connect it with your Gmail account and a FireFox sidebar.

It’s easy to edit existing tasks, add new and to go back and look at your history. One thing I discovered it was very handy for was making a packing list when going on holiday. My girlfriend kept nagging me, remember this, remember that. But I just used my todoist and she was very surprised that i remembered everything.

And best of all, it’s free. Keep track of your todolist, check out Todoist.com.
