The Parker Planner app for iPhone is a calendar, to-do list, and note-taking app all in one. This home screen shows the current day (the current day always appears with color; flip to another day, and that red bar turns gray) in three panes for your calendar, to-do list, and notes.
Parker Planner can pull in your iPhone's calendar appointments.
You can also see the Parker Planner calendar in list view.
Another viewing option is the month calendar. The various colored dots represent entries from different calendars.
The to-do list can also be viewed in list form, where you can see more of what you wrote about your tasks.
This screen in Parker Planner shows the different calendars on this iPhone that you can import into the Parker Planner calendar.
