Best Free Timer and Alarm Clock


Lots of people use their computer for almost anything. So why not use it as an alarm clock, waking you up from your dreams? And what about reminding you to go for an appointment right away before it's too late while being engrossed in something else on a computer?

There are lots of alarm clocks on the internet, but most of them don't wake your computer from standby or hibernation. Why leave your computer running all night just for one important task: to wake you up?!

These are freeware programs which might be useful and interesting to you if you don't like that waste of energy either.

WakeupOnStandByWakeupOnStandBy, like the name already says, it wakes your computer from standby or hibernation. You can set this program to run whatever you want after it wakes up. It's also possible to set it for different time schedules, using multiple instances of the program.

You could use it as an alarm clock by starting up internet radio or m3u-playlists. It works nicely in combination with another one of the developer's free tools, called Toff, which puts your system to sleep.


Alarm Clock of JusticeAlarm Clock of Justice is a computer alarm clock that can wake your computer from standby or hibernation to play a customized alarm. This includes any file type.

The program has a customizable snooze as well as a standard activated, volume-level control.

Not all soundcards support this volume control though, so you should test if your card supports it or you have to turn this option off.

Simple Alarm Clock, a really simple version from the same developer that just does what it's supposed to: Waking from standby/hibernation and running the file you want.


Free Alarm ClockFree Alarm Clock has a clean and simple user interface, combined with useful functions such as loop and snooze, repeat alarm, wake up the computer from a sleep mode, turn on monitor power and adjustable volume.

This program has a portable version. You can download the zip file, extract it to a folder and run it right away without the need to install. All your settings are saved to this file Data.ini in the same folder.


Other alarm clocks (without waking from standby):

Marxio Timer "Program executes action specified by user (turn off, restart computer, hibernate, suspend, logout user, lock desktop, display text, play sound, run other application). It's run at time specified or when idle time elapses. It can also repeat actions after n minutes or start countdown seconds to execute action."

Note: The vendor's own download location is now offline. I checked the Softpedia link and this was still working as of 30th of December 2012.

The clock is in 24 hour format, so you know when the alarm is going to sound. Another great feature is that the time is in your computer time, not the server time. Also, if your internet connection goes down, no worries, your alarm will still go off.

I just tried TimeLeft today:
md5: 4537ba277cdebfb8ba74687158871891
v3.62. Doesn't look like it's been updated since 2012.
DL size is 2MB.
URL, DL install file, and resulting installed .exe all pass
I like it because it has
- stay on top
- drag outside window--so i can put it on an empty part of the task bar
- transparency
- resizable
It does reminders, countdowns, timers, stopwatch, stickers, and regular old clock.
It is an installer, but it has the option to install portable. Curious choice.
It did, unfortunately, open their FAQ page upon "installation" (I chose portable).

(why does my text look so small in this edit window)

ok, i have moderate computer abilities. i don't have outlook and i do have a dell pc w/ windows. i need to set a recurring alarm to remind me about bills due on a certain date. is there any website or free download that would do this? just want to tell it "allstate due each month on 10th" or the like. any suggestions? tired of paying late fees or having services cut off! ;-)
