Feature packed

Syncs calendar events with the iPhones native calendar, has a valuable week view that shows both tasks and events for the week, allows colors of calendars and tasks to be changed and labeled, tasks can be copied (though a repeat feature is absent, unfortunately), first day of the week can be selected as Monday or Sunday, completed tasks can be shown as checked off or hidden, no wifi or 3G necessary, tasks can be ordered by priority, due date, etc.

Clearly, this app offers a lot and I believe it was well worth the purchase. I use it to keep track of assignments (I assign a different color for each class) as well as events. It functions best as a to-do list (I see no problems with the native iPhone calendar, and this app does not really attempt to improve on it), but it allows you to view it side by side with the calendar events, which makes the iPhones calendar unnecessary. I love it, I use it everyday, and I highly recommend it to anyone looking for an electronic replacement for their day planner.
