From the developer:
Better Together: SmartDay integrates Appointments, Tasks, Lists, and Notes - all in one app. And keeps them synced with SmartDay on your iPhone and SmartPad on your iPad.
Forget about boring calendars and to-do list apps that keep you glancing back and forth. SmartDay automatically schedules your pending tasks into the free time between your appointments, and displays them in one simple view that flows like your day.
