SmokeLess: Move Your Last Cigarette Away From Bedtime

Field notes

SmokeLess uses a staged cutoff rather than a quit date: the protected period begins one hour before bedtime and advances toward five hours at a user-selected pace. Users can set different weekend bedtimes, disable windows on selected days, and receive cutoff reminders. The site describes Lock Screen and Dynamic Island support, with behavior varying by iOS version. Its evidence section names the studies behind the nicotine half-life and bedtime-smoking claims, while explicitly labeling the sleep findings as associations.
