To-do lists are great when you can get everything on the list done by yourself.

But when you need help or want to delegate, you need Astrid Tasks. This Web app lets you create and manage to-do lists, but it also lets you share lists, assign tasks to others, and ask for help when needed.

Astrid Tasks is available for smartphones, in the form of a Chrome Web app, and in a Web version that works with most other major browsers.
