Desktop Timer

Desktop Timer is a software tool, developed specifically so as to help individuals activate an alarm when a predefined period of time ends.
This utility is portable, meaning you can easily bypass the installation process. As a result, the Windows registry is not going to be affected by this app in any way, and there will be no leftovers upon its removal from the hard drive.
Aside from that, if you drop the program files to a portable storage unit (USB flash drive), you can use Desktop Timer on any computer you can get your hands on, by simply clicking the executable.
The interface is clear-cut and highly intuitive therefore, allows even people with no experience with computers, easily find their way around it.
You can input the time period from which to count down, by clicking the “Set” button and by using the left and right arrows on the keyboard, as well as the digits. The maximum time period one can set is 99 hours and 59 minutes and seconds.
The “Start” button commences the countdown period, while it is also possible to reset the time, or hide the clock in the system tray, so as not to become obtrusive. If you click the systray icon, a context menu pops up, which enables you to load a new alarm, loop or test it, exit the program, as well as access the online Help contents.
As long as you place a WAV file in the same folder with this utility, you can easily use it as a new alarm. You can use items from your hard drive, or download some from the developer’s website.
All in all, Desktop Timer proves to be an efficient piece of software. It does not require many system resources, it can be easily hidden when not needed and response time is very good.
