You work shifts, but your life is more than your shifts. ShiftLife sets up your rotation and plans all 24 hours of every day, so sleep, family and your own goals fit around the schedule. Made for nurses, doctors, paramedics, police officers, firefighters, security staff, factory and call-center workers. SET UP YOUR ROTATION IN A MINUTE • Ready-made patterns: 12/36, 12/24, 24/48 Kelly, triple rotation 08-16-24, Pitman 2-2-3, DuPont, Southern swing, 4-2, physician on-call, fixed hours, or your own pattern. • Your whole cycle on one screen: day shifts, nights, recovery days and days off, color-coded. • Give your rotation and day types your own names. ALL 24 HOURS, PLANNED • A 24-hour template for every day type: sleep, work, commute, family, exercise and focus time. • Change your shift hours and the plan stays; in most cases blocks line up with the new times. • Shift ran long? One tap logs the overtime and the rest of the day adjusts. SLEEP AROUND NIGHT SHIFTS • Sleep is planned in 90-minute cycles, so you know how many cycles you get after a night shift. • Sleep against your goal across the whole cycle, with sleep debt. • Connect Apple Health to see sleep, steps and active energy. Sleep is written to Health only with your permission. LEAVE, SICK DAYS, SWAPS • Log leave, sick days, guest days or shift swaps on the right calendar day; your cycle stays intact. ROUTINES AND GOALS • Repeat routines by date or by day of your cycle. • Break goals into projects and milestones; your focus time is spread across the cycle. • The Today screen shows the current block, your next step and the day at a glance. PRO • Send shifts and handovers for 90 days, and timed plan blocks such as sleep, family, exercise and focus time for 30 days, to Apple Calendar or Google Calendar (one-way). • Home Screen and Lock Screen widgets. • Weekly report, cycle chart, CSV export and archive. • All themes, plus unlimited projects, plans, milestones and notes. Core planning is free and needs no account. Pro is available monthly, yearly or as a one-time lifetime purchase; the yearly free trial is shown only to eligible App Store accounts.
