The free version of ToodleDo (which is all I’ve used to date) is VERY robust in its feature set, and I’m quite pleased to have parted with $2 for the superb web application.
– Pro accounts are either $15 or $30 per year, depending on features
(Key item for me is “Full GTD Support”) A full page explanation is available about the GTD system and how ToodleDo integrates with it. – feature comparison with other task managers including Remember the Milk. – has iPhone application ($2 for the holidays, normally $4) – supports collaboration: share access rights to tasks, also accept tasks from others (others have read-only access unless they also have a pro account) – is a web-based, explicitly GTD style task manager – NOT designed for sharing or collaboration: “Mainly for the home/office user who doesn’t need to share or collaborate with a team.”
– has Windows and Macintosh software clients, as well as an iPhone client – costs $20 as one-time fee, no ongoing fees or subscriptions
– does not have a software client for Mac or Windows – Has an iPhone client for Pro account users, which costs $25 per year
These were some of the primary differentiators I identified for my three “finalist” GTD applications. In addition to “Remember the Milk,” the other applications with similar (but inferior) functionality to Toodledo compared in this chart include: Note all of these do NOT, however, have an iPhone application, which was one of my important criteria in making this selection. The Toodledo website has a nice comparative chart with features listed for other web-based GTD solutions. The three different websites and applications which were “finalists” for my GTD application solution were: This flowchart from the webpage visually explains the GTD process of dealing with input on a regular basis: It is one of the most concise summaries of the system I’ve read to date, contextually explained for Toodledo.
The Toodledo webpage explaining how to use the website and iPhone app to implement David Allen’s GTD organization system is superb. The website and application I’ve settled on after a bit of research is Toodledo, which was recommended to me a few months ago by James Deaton. So, one of my holiday goals was to find and begin utilizing a new GTD application which would integrate wonderfully onto my iPhone. Once you start writing things down in other places or trying to keep them memorized but not recorded, you’re sunk. A GTD tool cannot work unless it is used ALL the time to manage tasks. (A beta iPhone app is under development by a 3rd party, but so far nothing has been released.) The site remains a true “web app” as all iPhone applications were before the release of the iPhone SDK. Unlike many other GTD solutions, the developers of 43actions have NOT created an actual iPhone application which syncs to the web. The site is a web application for the iPhone, and does work OK, but I found it required too many connections and clicks to the web to function quickly and transparently. The GTD application I’ve used most extensively (but eventually abandoned) was.
