You need a calendar, to-do list, AND notes to plan properly. Three distinct things that come as 3 separate, standard apps on the iPhone. Wouldn't you like to see a todo list while you plan, or take notes about a calendar event and view them all at the same time?
Now you can. Parker Planner for iPhone, the only planner app with a calendar, todo list, and notes all on one screen! Use life wisely.
Since 2006, Parker Planners has sold wonderfully useful pocket-szed paper planners. You can still buy them at our partner site, HERE.
