Claris Organizer has been in use for a long time on Apple machines. It has a good set of basic features for calendaring. Given its age, there a number of significant missing features, in particular there is no support for any kind of calendar sharing amoung multiple users. This means there is no support scheduling meetings for user groups.

Despite its age, Organizer provides fundamental calendaring functionality as well as any of the newer tools. Its features for color-coded categories and filter-based search are in fact exemplary. Organizer does not provide multi- platform operation, since is is an Apple-only product.

Good Features:

• covers the basics fine
• provides good printing functionality
• allows overlapping items and does a pretty good job of displaying them
• provides pretty good functionality for recurring items, but monthly recurring items cannot be specified that well; for example a recurring schedule on several specific days of the month cannot be done easily
• provides good functionality for item categories, allowing naming and color coding
• provides good functionality for filtering, allowing user-defined views that can include or not include particular properties of scheduled items; for example a custom view can be defined to show only items of a particular category with titles containing a certain text pattern
• overall it's nice and simple, without a lot of superfluous features

Bad Features:

• allows only one view of one calendar to be open at a time; this is a significant problem
• has only one level of undo/redo
• the only kind of lists are for tasks
• provides a calendar "navigator" in the form of a small monthly view that is not very useful
• provides a "special date" type of scheduled item that is not useful given that is not significantly different than the "event" type of item
• provides a "contact list" feature that is not integrated with any external address book tool, making the feature not very useful
• provides a "notes" feature that is not well integrated with the calendar; specifically, notes can have a date stamp, but are not specifically associated with scheduled items

Missing Features

• no import of other calendar formats, including no import of plain text
• no place to put the location of a scheduled item; it must be squeezed into the title
• no details or notes field for scheduled items
• no yearly view
• no multi-user features at all, including no meeting items on calendar, and necessarily no user or group administration functionality
