Auge

It's almost common knowledge that spending long hours in front of computer screens is not exactly ideal for our health. Of course, in the short term you're eyes take most of the hit, therefore eye strain is the most noticeable negative effect, but, depending on the time spent daily in from of your computer, neck, back, shoulder strain might also arise.

The good news is that there a few things you can do to reduce most of the unwanted effects described above, like, for example,  use the 20-20-20 rule. In short, this method dictates that you take a 20-second break, every 20 minutes and focus your eyes on objects or places at least 20 feet (ruffly 6 meters) away.

If this sounds appealing, then you might even consider employing the services of a tiny app called Auge. In short, this unobtrusive utility runs in the background and prompts you every 20 minutes to take a 20-second break, by displaying a simple countdown timer. Once the countdown is finished, the board automatically disappears.

The app does not require installation, and it should work on all versions of Windows without problems. Unfortunately, the app does have some shortcomings. For instance, there's no GUI present, and the app does not even feature taskbar integration. This means that there's no practical way of pausing the app's timer, hence, you must terminate the process altogether and relaunch it afterward, if need be.

All things considered, Auge is a straightforward and fairly useful application which forces you to use the 20-20-20 method in order to prevent eye strain, as well as other types of physical pain usually associated with sitting in front of a computer for extended periods of time.  It's not a polished app by any means, but it does get the job done with just one click.
