Big Meter Pro is a small and handy application for you to know your CPU, memory, and disk usage in real time and in a visual way. It allows you to establish system alerts for certain important events, like when the CPU reaches a high usage percentage. It also allows you to set the exact time for an alarm clock alert, and it can display detailed information about your CPU, memory or disk, too.

The program's user interface is pretty small and you can drag and drop it anywhere on your screen. It can be configured to stay always on top or otherwise, and you can minimize it or close it at any moment. However, you have to right-click on its main window or on the icon in the system tray area to display its pop-up menu and get access to the remaining options and to the "Settings" window.

Through those options, you can configure what to show in the program's window – the CPU usage, the RAM memory usage, the partition usage, or an analog alarm clock which displays the current time. Furthermore, through the "Information" sub-menu, you can launch a separate window displaying very detailed information about your CPU, memory or hard disk.

On the "Settings" window, you can configure some parameters related to the general working of the program. For example, you can set it to run on Windows start-up, enable or disable the Smooth option (which provides a better visual presentation but takes up more system resources) and define the drive letter to show information about. You can also enable alerts and set the CPU, memory, and disk usage percentages. Finally, you can set the time for the clock alarm, too.
