I previously used Google Calender & Google Notebook for my GTD, but I’m using “Things” beta desktop application now, hopefully they will provide IPod syncing option soon.

There’s a regular column at “About This Particular Macintosh” that keeps track of GTD apps that has good info.

I’m a happy OmniFocus user.

Things.

Trust me. Things. All others are worthless!(1)

(1. To me. YMMV.)

OmniFocus for me. I’ve used several others, and they were good, but OmniFocus to me seems the most versatile when it comes to capturing tasks in a variety of ways.

Omnifocus for me as well, sync’ed to iCal and from there to my windows mobile phone

I love this app. Normally I have my GTD system setup with one particular application for tasks, but I still download others and play around with them.

But Things has changed that for me (thankfully). This is the first GTD app that I have used for more than a month where I stopped paying attention to all others. I’m finally working on the items in my list, rather than on the list itself.

43 Actions. Have just found it, and love it. Use it on my MacBook Pro and iPod Touch. http://43actions.com/account/login

Another deadline looming, so I switched tools to avoid having to think about it too much. Again.

I love OmniFocus, but I kept messing up my projects and contexts. The projects especially: I tried organizing them into folders, and subfolders and then the actual project had tasks and subtasks… and in the end I spent too much time wondering where to put my stuff.

It was hard to switch to TaskPaper, because I lost so many cool features (plus all the money I spent on OF). But after a couple of days of using it I feel the limitations have set me free.

Until the next deadline, anyway.

I too was using OmniFocus. But after seeing a posting from CSGiles in the Getting Things Done Public Forum, I switched to using Notes and To Do capability in Apple Mail (OS 10.5).

I have a note for each project, each w/ a brainstormed list of NAs. I activate NAs one at a time, i.e. turn the project’s next NA into a To Do item. As the NA is activated, I assign it to the appropriate context calendar. When the to do is completed, I check it off. I’ve also got a note for Singletons.

To keep my list from having too many completed items, I deactivate NAs during clean-up. To do this, I open the project note, highlight the completed NA, and click To Do again. It’s no longer a To Do. Then I highlight the next NA, click To Do, and assign it to a context calendar. Downside is that you have to manually activate NAs whereas OmniFocus automates the process. I don’t mind it though.

I’ve got two folders, Personal and Professional, into which I file my Project notes. I also have folders: Completed and Someday/Maybe. When I complete a project, I move its note to the Completed folder. I have a note in the Someday/Maybe folder for ideas that may be singletons or projects for which I don’t feel like outlining NAs yet. I also have a note in the Completed folder for completed Singletons.

Having used it now for a month, I prefer the simplicity of this system.
