The iPhone seems perfect for task management apps, and that's exactly why there are tons of them. Easy Task offers a few more functions then most of the task apps out there currently, including the ability to sync up with an online account, making it a lot more useful then its competition.
When you load up the app you are shown the main dashboard. At the dashboard you can see what you've got set out for you to do today, the inbox listing those events again, then a listing of different days away that you have more tasks. There's even an area for what's past due and what's completed as well. Under that you can even sync your tasks online just by registering a username and password.
If you're up for customizing the different areas of the task manager, you can change the projects and context in which you list a task. Those effect the options that you can select when you add a task. When you click Add New Task you can name the task, set the fields, set a start date and due date, rate the importance, and even add notes. Once you've completed a task you can go back into it and set whether you've completed it or not.
Compared to the other task management apps, this one is pretty great. Having the ability to sync up with your computer makes it very useful and gives you the ability to take that info elsewhere. But since you can easily take advantage of Google Calendar or even the iPhone calender, this app is an extra and not necessary.
