Best anti-RSI tool

I suffered from back pain so i needed to take regular intervals from PC use. I tried many similar programs but this is by far the best i’ve found. I think its also better than its Windows competitor, Workrave. In contrast to what has been said in other reviews the application is completely free for basic functionality. If you want to use advanced features you can try as many times as you want one at a time, but if you become a supporter (donating from 2.99$ to 12.99$ at your choice) all the advanced features are unlocked for lifetime.
If you suffer from RSI or simply need to take frequent breaks this is the best tool you can get for free.
Kudos to the developer!
