I've got this app for about a year now. Previously tried Intermission and Time Out. Apps like these must be carefully designed, since they always border on annoying/stressful. LookAway is easily the most finetuned app in this space.

- It turns itself off outside business hours.

- It has a thoughtfully designed heads-up notification that can't be confused with system notifications.

- It disables itself during meetings & videos.

- It waits for you to finish typing.

- When entering the break screen, there is 5 second cooldown before you can skip it, preventing you from skipping it out of habit.
