Omni recently released OmniPlan at a cost of $149, and iGTD is another popular offering, especially since it’s free. The problem I have with the whole GTD movement is that I feel like you spend more time organizing and categorizing and less time doing. Most of the applications I’ve looked at require a lot of time to enter tasks, place them in proper categories, customize the interface to your needs and simply living in the app to actually get any use out of them. You spend more time trying to help yourself be productive than actually accomplishing your goal of getting things done.
Getting things done with a little Anxiety
Getting things done (GTD) is all the rage these days. It’s all over the Web, with entire sites dedicated to helping you achieve a “honey-do”-free life. There are plenty of applications out there to help you as well.
