AntiRSI is a program for Mac OS X that helps prevent RSI (repetitive strain injury) and other computer related stress. It does so by forcing you to take regular breaks, yet without getting in the way. It also detects natural breaks so it won't force too many breaks on you.


This is an evolved version from the still free 2.1 version (available here:


* AntiRSI can be removed from the Dock and appear in the menu bar.

* Break windows appear on all connected displays.

* Larger break window, screens are no longer 17 inch.

* Possibility to disable micro pause or work breaks.

* Improved compatibility with media players.

* A natural break window (experimental). Helps with reading a lot from the the computer screen. (Feedback appreciated.)


AntiRSI is a reminder tool that can be helpful, but it is not a medical device. If you experience problems, please consult a doctor.

Fantastic for CTS/RSI

I suffer from carpal tunnel syndrome in my right wrist, and this application is absolutely indispensible. It’s a simple idea, but so incredibly well executed that it’s worth pretty much any amount they’d charge. At the base level, it makes you take short breaks often and a long break every hour or so — this is demonstrably good for people suffering from RSI/CTS. It’s very intelligent about detecting “natural breaks” (i.e. moments when you’re not using the keyboard) and will incorporate those natural pauses into its timers, meaning you can skip some short breaks if you took them anyway. This helps you stay more productive / focused by eliminating redundant breaks.

If you have RSI/CTS, you already know how much of an impact it has on your life. Software like this helps you manage these chronic problems. Well worth installing.

Perfect level of interruption

I really love the notification system used by this app. Every other similar app either:
- pops up a small notification that I never notice or
- pops up a modal dialog that steals my keystrokes or otherwise totally interrupts my work

This does a perfect job of making itself noticed but still allowing me to complete whatever thought I'm in the middle of at the time. I also like that I can quickly snooze the notification but it's persistent enough that I can't really keep ignoring it.

The only thing I'd like to see is some sort of AppleScript or other trigger mechanism -- I use this as part of a Pomodoro time management system, and it would be nice if I could have it trigger events in other apps when I hit or complete a break.

Needs fixing—even more broken under Yosemite.

I've been using AntiRSI for years—it's an essential Mac app if you are struggling with RSI. The author has abandoned it, unfortunately, and it doesn’t work properly under Yosemite. The text on the break display don’t display properly anymore.

• Text doesn’t display on Yosemite
• Hold focus feature (which is nice) needs to switch focus to your app afterwards. Otherwise anti-RSI is requiring more RSI-inducing clicks to use!!!
• Also, I wish the micropause slider could register at smaller, perhaps 30-second increments.

I should note that I’ve been using this for years, and have previously made a large donation when it was donation-ware and then bought it again on the app store, but am sad the author seems to have abandoned this software.
