It actually works, great product!

I’ll admit that I was a little skeptical starting the 20-20-20 rule for it’s effectiveness in preventing eye strain. I started using this app at the begining of a coding class and used it for several weeks. Yesterday I ignored it’s promptings all day and today I TOTALLY feel the difference. I would recommend this for anyone who spends several hours a day lookin at a computer screen. This will save you many headaches in the long run. Great app!
