Time management methodologies never get old. People want to be more productive and to accomplish more things in less time. We already covered some to-do apps for the iPhone (in this post and in this one as well) that use these methodologies. However, the great advantage but also the great flaw of to-do apps, is that they force you to focus. Be it a single task or one project, to-do apps sometimes fail to give you the “big picture” or to help you take care of smaller things.
