Cook Timer Portable can run from a cloud folder, external drive, or local folder without installing into Windows. It's even better with the PortableApps.com Platform for easy installs and automatic updates.
Cook Timer has presets for 3, 5, 10 and 15 minutes and lets you set a custom time in hours, minutes and seconds. A progress bar lets you easily see the time remaining visually. An alarm will beep briefly when time is up. It can optionally be set to beep until you disable it. The timer can also automatically restart once time is up allowing you to mark off a specific amount of time continuously.
