Got-2 Task Management- enables you to create list and even sub-list of the things you have to do. You can cross of the list you have completed with the 3 different views you can use. I usually use the agenda view which I think makes things even more simple. But the list view and even the geographical view is great
Mara Tick is a simple free list manager. You can create your own set of list for anything you want. Creating a new list is so easy you just enter a name or description of your list and it will ask you set a deadline on when you should complete the list. If you set a completion date Mara Tick will even display a reminder in your Blackberry's calendar on when it's due
