Calc turns the Palm into a standard 4-function pocket calculator with three shades of purple and blue buttons contrasting with the two red clear buttons. It supports square root and percent keys and has one memory. It also has an option to display a running history of the calculations, much like the paper-tape calculators that were once common. Date Book shows a daily or weekly schedule, or a simple monthly view. The daily schedule has one line per hour, between user-selected begin and end times. Clicking on an empty line creates a new event. Empty lines are crowded out by actual events, whose start and stop times are shown by default bracketed in the left margin. The newer Calendar app adds the following features: New Day view, use of categories for events, event location, event can span midnight, event details, birthdays as timeless events. It supports time zone designation for events, a feature lacking in some more recent competitors. An event, or appointment, can be heralded by an alarm, any number of minutes, hours or days before it begins. These alarms sound even when the unit is switched off. Appointments can recur in a specified number of days, weeks, months or years and can contain notes. Expense tracks common business expenses. No totals are calculated on the Palm. The user must sync with a host computer and view the expense data in a worksheet (templates for Microsoft Excel are supplied). HotSync integrates with the user's PC. Usually activated by a press of the physical HotSync button on the Palm's cradle (a dock station), this application communicates with various conduits on the desktop PC to install software, backup databases, or merge changes made on the PC or the handheld to both devices. It can communicate with the PC through a physical connection (USB on newer models), Bluetooth or IrDA wireless connections, and direct network connections on devices with networking capability. In addition to the conduits provided by the licensee, developers can create their own conduits for integration with other Palm OS applications and desktop products. For example, a time tracking package could provide a conduit to communicate information between Palm OS and Windows executables. A Backup conduit included with the HotSync software backs up (and restores, if necessary) most of the data on a Palm OS device. This
