Computer Timer

Computer Timer is a simplistic piece of software that gives you the possibility to schedule reminders with messages and audio.
It's practical for those who are looking for easy ways to remember important upcoming events, such as meetings.

Doesn't require setup

There is no installation involved, so you can launch the program as soon as you download its package. There are two scripts files that can be separately accessed, with the difference being that one features audio reminders and the other one doesn't.
There's nothing to be said about the interface, since it's clear that the developer didn't want to focus on appearance but only on functionality.

Set the countdown time and custom message

You're welcomed by a plain-looking window that asks you to enter the countdown time until the reminder (in minutes).
After confirming this dialog, you can input the message to display when time's up.
While the countdown is running, you can carry on with your typical desktop activity without other interruptions, since the app silently runs in the background.

Speaks your custom message using a robotic voice

Once time expires, your custom message pops up on the center of the screen. If you have opted for audio mode, then a male robotic voice speaks your message right before revealing it on the monitor.
In the following step, you can enter a command to execute or just quit to the desktop if you've finished planning reminders.

Modest event reminder with basic options

This is where Computer Timer's functionality ends. Unfortunately, it doesn't integrate features for setting up multiple reminders at the same time as well as managing them from a window.
Although it takes a rather rudimentary approach toward task reminders, the app gets the job done and can be easily configured by users, even those with no previous experience in such software.
