My iPhone got a little bit better to use as a tool yesterday.

I’ve written before about how I use my phone as the centerpiece of my strategy for staying in touch and keeping organized. A big part of this is using a task management application to help keep track of all my projects.

My project management is handled by Toodledo, a cloud computing application where I keep all my projects, to-do’s and notes. One of the great things about Toodledo is that to-do items can be sorted into tasks and sub-tasks – really important if your projects are not always simple.

There are a lot of iPhone to-do apps, many of which will happily sync with Toodledo. I’ve tried a whole bunch of these and my favorite has always been Todo by Applgo. I couldn’t even say whay I liek it best, it is just so well thought out, easy to use and easy to read. Until yesterday it had a huge drawback for me – no sub-task support. Because I use sub-tasks extensively in Toodledo, it is essential that I don’t lose that formatting on my phone. Toodledo’s own iPhone app does have sub-task support so that has been my iPhone app of second choice for a while.

You won’t believe how happy I was when the App Store let me know there was a new version of Todo available – even better it now supports those elusive sub-tasks. I quickly downloaded the new version and it was time to play. Just as an aside, I love how simple Apple have made updates. Having come from the Windows Mobile world, this is such a treat!

Anyway, I must say I’m really happy with the new version of Todo – it is doing just what I would have wanted. The attached screenshot shows the sub-tasks that I’ve assigned to my Totally Incorrect project – a kind of preview of blog posts to come in the near future.

There are several really good task management apps for the iPhone and at the moment Todo is my favorite again.

Quick update – after using the new version of Todo, I’m still enjoying it. I do have a feature request though: Toodledo’s iPhone app has a nice feature that lets you quickly place a star next to any item – great for flagging “next actions” if you are using the GTD technique. I would love Todo to have this feature as well  </hint>

Are you an iPhone (or other smartphone) user? What is your favorite tool for task management?
