Time Out came through where other apps could not. Since I have a bad habit of not taking regular breaks, I tried reminders and Pomodoro timers but would just hit “snooze” or “pause", and even Time Out didnt work for me initially since I could still see through the transparency and/or click the button/s to postpone. But once I disabled the buttons and set the opacity to 100%, I was finally able to force myself to get away from the computer since, with buttons disabled, the only way to hide the Time Out screen is to basically restart your computer, or just wait it out (which is the whole point, ha).
For anyone who faces similar obsessive work habits and feels the physical results (dry eyes, RSI, carpal tunnel) or just an unhealthy, unbalanced feeling of burnout in their work day, Time Out might be your answer. And I highly recommend the Pro version as the hourly settings reset of the free version is incredibly annoying!
