Got-2 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.
What makes Got-2 even more unique is its GPS integration or location base alerts. Imagine being alerted to get the dry cleaning since your near the area. Its a feature a lot of people need if you want to save time and maybe save you from making a second trip with your car.
