Paint a few days of your shifts and Owlday fills in the months ahead. Around every night block it plans when to sleep, when to nap, when to stop coffee and when to keep the light out, using your own shift times and the sleep you need.
Two days, two nights and four off, Pitman 2-2-3, DuPont, Kelly, 24 on and 48 off, earlies, lates and nights. Paint it once; change single days when you swap.
A nap before the first night, bright light early in the shift, the last coffee six hours before sleep, dark glasses on the way home, and a short recovery sleep after the last night.
Night and weekend hours, extra and short time, a pay estimate with your own extras, and the days you and your partner are both free.
Night work moves sleep into the day, and the hardest days are the first night of a block and the day after the last one. Public advice for shift workers is consistent: a short nap before the first night, bright light in the first half of the shift, no caffeine in the hours before sleep, a dark and cool bedroom after the shift, and a short sleep after the last night before going back to a normal bedtime. Owlday puts that advice on the clock of your own rota, so you see it as times, not as tips. It is general guidance, not medical advice.
Your rota stays on your iPhone. Reminders are set on the phone. You can save a backup file and restore it on a new phone.
