ClockSmith Lite plays the Westminster chimes and tolls the hour. The chimes can be configured to play quarterly, every half hour, hourly, or they can be turned off. The tolling of the hour also has an on/off switch. ClockSmith Lite has its own volume control allowing you to configure it to provide a gentle reminder of the time, to be heard clear down the hall, or anywhere in between.
ClockSmith Lite is small and efficient and will happily run in the background while giving you periodic reminders of the time. It places an icon in the system tray from which the chimes can be configured allowing you to close the main window and free up desktop and taskbar space also.
ClockSmith Lite is free, so give it a try and let us know how you like it.
