Which routine fits?
Dia Key is intentionally narrow: it is for a person who wants gratitude writing to be the replacement action before a social feed or other selected app. ScreenZen may suit someone who wants granular schedules, limits, and tracking. Neither app is a medical treatment or a guarantee that a person will never override a boundary.
