As you'd probably guess, this application monitors Web pages and notifies you of content changes, but it doesn't highlight updates. Web Page Change Monitor's no-frills interface has a bar for you to type the URL of the site you want to monitor, which it displays below. The program checks on just one Web site at a time and only allows for monitoring in minute intervals. Notification is simply a pop-up box at the determined time interval with a two-word message: "Site changed." No further details are given about the changes.
It would've been ideal if the message box automatically popped up every time the page was updated and if modifications were highlighted. Since this is not the case, you'll need to constantly check the program and distinguish the updates yourself. In addition to that, the help file is missing in action. While this watchdog worked relatively fine, it isn't difficult to find more competent software with this type of functionality.
