## What is Owlday?

Owlday is a shift calendar for people whose week does not start at nine. Paint a few days of your schedule: two days, two nights and four off, a Pitman, a DuPont, 24 on and 48 off. Owlday spots the pattern and fills in the months ahead. Change a single day when you swap, pick up extra hours or take leave, and the rest stays as it was.

Every night block gets a sleep plan. The dial on the Today screen shows your shift, your main sleep, a nap before the first night, the time to stop coffee, when bright light helps and when to keep it dark on the way home. After the last night it plans a short recovery sleep and an early bedtime, so you are back on days without losing your whole day off. The advice follows public guidance for shift workers and adapts to the sleep you need, your commute and whether you are an early bird or a night owl.

Hours add themselves up: planned hours, night and weekend hours, extra time, short time and the balance against your contract. Enter your hourly rate and the extras for nights, weekends and public holidays, and Owlday estimates the month before tax and exports it as a CSV file.

Add the schedule of a partner or a friend and Owlday lists the days and evenings you are both free over the next two months.

Reminders before each shift are set on the phone itself. There is no account, no sign-in and no server: your schedule stays on this iPhone, and you can save a backup file whenever you like.

Owlday Pro adds the sleep plan for every night of a block with wind-down reminders, pay estimates with extras, a second job, more shared schedules, calendar export and the year view. Your schedule, your hours and tonight's plan stay free.

Owlday Pro subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can cancel at any time in your App Store account settings.
