## What is OnOff?

Enter your rotation once. OnOff fills in your work days, nights and days off five years ahead.

Built for rotations with uneven blocks: 14 on and 7 off, two weeks of days then two weeks of nights, or something like 4 nights, 3 off, 3 days, 1 off. Add the blocks in order and the cycle repeats from your start date.

SET IT UP ONCE
• Pick a common rotation or build your own from Day, Evening, Night and Off blocks of 1 to 90 days
• Set the day the first block started. A past date is fine
• A four-week preview shows the result before you save

SEE YEARS AHEAD
• Month after month for the next five years, each day marked with its shift
• Today's card shows your shift, which day of the stretch you're on, and when the next change comes
• A home screen widget shows today and the days ahead

WHEN A DAY IS DIFFERENT
• Tap any day to mark leave or swap the shift for that day only. Your rotation stays as it is

PRO, ONE TIME
• Several rotations, for you and your partner or a coworker
• Send two years of shifts as a calendar file (.ics). Open it in Calendar or send it to family in Messages
• A one-time purchase. No subscription, no renewals. Restore on any device with the same Apple Account

PRIVATE
• No account and no sign-up
• Rotations are stored on your iPhone and copied to your own iCloud key-value storage
• No ads, no tracking, no analytics. The app asks for no permissions

Requires iOS 18 or later.
