I'm looking for a free or open source lightweight timer compatible with Windows 7.

Essentially I'm looking for a pomodoro-type timer, but I don't want 30 minute intervals; I want to set my intervals. I'd like for it to alert me somehow visually that the time is up, even if it's running in the background.

Basically I want a program that will tell me to get up and stretch and/or rest my eyes every hour or x minutes. I'd like it to restart when I tell it that my break is done. Pausing would be nice, but not essential. I'd like it to be lightweight. I guess it could be a webapp. And I'd like it to not lock me out.

I tried workrave, but it doesn't alert me well enough. And google timer only has audible alerts while I often have the computer muted.


  1. Free
  2. Visual Alerts on Windows 7
  3. Capable of 1-hour intervals, even if it only uses fixed inherent schemes
  4. Reset the interval when I tell it to
  5. Pausing

I use an open source timer called Hourglass. It has a great interface and is very lightweight. It can alert you visually or using audio alerts as well. It meets all of your requirements including,

  1. Free - It's open source.
  2. Visual Alerts on Windows 7 - Popups, flashing, audio alerts which can all be configured.
  3. Capable of 1-hour intervals, even if it only uses fixed inherent schemes - it does basically any time frame you give it.
  4. Reset the interval when I tell it to
  5. Pausing
