Schedule Management Done Right

I would have to say that the feature I find most appealing in Calendars 5 - Smart Calendar and Task Manager with Google Calendar Sync is the Natural Language Input.

This enables you to schedule tasks and appointments simply by typing in the specifics, so for example you could type something like “Meet mom at home at 5:30pm,” and your appointment will be automatically scheduled.
