Stop procastinating and get work done every 25 minutes!
Focus mule locks you on a url or website for 25 minutes then gives you a 5 minutes break which allows you to visit other websites. Once 5 minutes is done, it locks you back to the website or url for another 25 minutes for another cycle. Once you complete 4 cycles, you take a 15 minutes break.
A very effective and well researched method to avoid procrastination either by visiting social medias or many other time wasting sites.
