I love Angelic Retreat I have been using it for a long time now and every time I change OS one of the things I re-install is this software. I love the way it makes me rest every certain time from my computer. I also combine it with the Pomodoro technique to have 25 minutes of work and 5 minute breaks, which helps me a lot. I prefer this to other similar software because it also give me some freedom to choose when I don't want or don't need a break. Highly recommended and thanks to the developer for such a nice and handy product.
