What mobile list manager do you use?

I use Action Lists on the iPhone, which syncs to Toodledo as the cloud storage. This client follows the GTD methodology, makes it very quick and easy to enter tasks into an inbox, and nicely displays lists of next actions by context or project for on-the-go decisions.

With the ToodleDo website, I can easily do my weekly review on a larger screen.

I voted OmniFocus since I use that on my iPad for personal GTD.

For work, I have been issued a BlackBerry (Torch) which is sync'ed with Outlook 2007 through my employer's Microsoft Exchange Server.

I was using Doit.Im and ActionComplete.

I paid for 6 months of Doit.im and 1 year of ActionComplete.

Today ActionComplete fits my needs better (better Context handling).

i am using OS Reminders to Outlook

I use Nozbe which syncs so well with Evernote where I house my reference files and project support.

I use the task list in my palm Tx, synchronised with Outlook on the desktop

I use Evernote because for me is immediate and simple.

I've used Touchdown but I wanted to keep my Calendar's in sync. The Google calendar & Toggl record of tasks completed are integrated into Outlook's overlay mode.

I just signed up with Astrid this week, and as a result of doing that was inspired to reconsider using GTD principles after some time away from it. I previously was using RTM, before that Toodledo. So far I think I like Astrid better, with one caveat: I'm an iPhone user and, though there is a fairly nice iPhone/iPad app, I didn't know before I signed up that the primary mobile platform the developers are focused on at this time is Android. (I signed up at the recommendation of and Android user.) That means that new features appear to be available to Android users first, with some lag for iOS users.

I've spent a good deal of time this morning setting up folders and lists that accommodate my current understanding of GTD, and assigning tasks accordingly. Time will tell if I can make it work efficiently.

Having gone through this process makes me wonder if I could do the same with RTM--I never tried. I might go back and take another look at it from that perspective.
