The Potential to Us Team has ManageList (iTunes Link) for the iPhone and iPod Touch in the iTunes App Store for FREE for a limited time.

ManageList is a manager application that supports the management of your events and schedules. Events can be added by simply tapping a few items and inputting text. Because your events can be managed by sorting into a list of things you’ll do today and things you’ll do next, maintenance is surprisingly simple, fast, and clear. With the ability to display an alarm to announce and confirm events ahead of time, all appointments are executed efficiently ensuring you’ll never overlook one again. ManageList is the perfect manager for you.
