RTM Works for Me
Having worked with a number of Task Managers and Project Management apps, I have settled on Remember the Milk. RTM syncs immediately in the cloud and is available instantly on my mobile devices and desktop computer. Sub tasks are available with the Pro version, well worth the cost. Excellent documentation and support.
