I'm looking for an online task list tool. What I absolutely need is the infinite number of subtask levels, because that's how my mind works. I don't need collaboration.

There are a lot of great to do list sites out there, but for some reason most of them have only one subtask level or no subtasks at all. I know about todoist, but its interface doesn't work for me. There must be many more, I guess. Links to desktop tools with the feature are also appreciated as long as they are cross-platform.

    @koiyu it's a good reference but this is more specific for the infinite number of subtasks.

  • You might want to give todoist another go. The app has improved tremendously over the last year or so and also has native apps for almost all platforms.

My personal favourite is the tasks within gmail. Google Tasks

The things I like best about it are the multiple levels of tasks and hotkey control. You are able to indent, unindent, move up and down just by the keyboard.

There is also multiple lists.

    Really, Google Tasks is the top voted answer? I found it simply not usable, switched to Producteev (that does not support infinite indirection) and never looked back.

I looked long and hard for something with sub-tasks. Toodledo is what I landed on. It costs about $15 a year for the version with subtasks, but it handles them well. It also lets me organize under folder so your heirarchial breakdown is Folder>>Task>>Subtask.

While infinite levels of subtasks would be nice, ie, assigning subtasks to tasks, this lets me do 95% of everything I need to do. If you google coupon codes, you can knock a few dollars off of the annual price as well, so works out to about one dollar per month. Not free, but hard to beat considering the value.


It is not a full featured todo app but it serves what you need... workflowy

  • By far the best solution here. WF could even be used to manage projects. Using it for years as todo list, shopping list, projects tracker, cooking recipes repo, trip prepare.. every part can be shared, and yI love receiving a daily mail with yesterday's changes

I really like Toodledo

Note: Subtasks are a paid feature.


My app of choice is Todoly. It's based on Todoist, but improves quite a bit in terms of usability and ease of use.


Not exactly what you're looking for, but MyLists offers some useful features. You can merge lists, create templates and pop out your lists into a side window, so you can always see them.


I know what you nedd - http://JoDo.im/


If you are using the IM-client for Jabber (GTalk, Miranda, Kopete, QIP, etc.), you can create and manage the TODO-lists directly from the chat window.

To create a list add [email protected] in your contact list.

To add a task to the list write to this user:

+ name of task
[description of the task]

The square brackets indicate optional.

In response, we obtain:

Task 1 is created.

Where 1 - is the number of this task.

To create subtask:

+number subtask_name
[description of the subtask]

Listing all tasks:


Mark task completed:

#ok number [comment]

Other commands can be found by typing #help

You can create any number of such lists for each area of life. Jabber-clients there for all platforms.

Thus we are able to quickly work with your ToDo directly from the chat window.

Service is free and has a web interface is available after registration with command:

#register your_login your_password your_email

If you do not have an account on any jabber-server, then you can get it on the same server.


Take a look at Task Resolver.

If your are searching for a to do list that will be the same on any of your gadgets, without additional software, then this service is just for you.
