4 On 4 Off Shift Work Calendar

Orbiday is a 4 on 4 off shift calendar and shift work calendar for people on rotating schedules — nurses, police, firefighters, EMTs, factory and warehouse crews, security and care workers.

Pick your rotation once and months of shifts fill in at once. No more tapping day by day.

■ Fill with a rotation
• 6 ready-made patterns: 4 on 4 off, Panama 2-2-3, DuPont, 3-shift rotation, weekdays (5 on 2 off) and 24 on 48 off
• Or build your own pattern of up to 56 days — tap a day to change it
• Choose the start day and fill 1, 3, 6 or 12 months
• Changed your mind? Undo right after filling

■ Month view
• Every day shows its shift color, name and start time
• Today and tomorrow at the top of the screen
• Tap a day to swap a shift or add a note (training, swap, overtime)

■ Home screen widget
• Today's and tomorrow's shift on your home screen
• The widget moves on with the date even if you don't open the app

■ Monthly totals
• Work days and work hours for the month
• Days and hours for every shift type

■ Share
• Send the month as an image to your family or team

■ Your shift types
• Day, evening, night and off are ready to go
• Add your own with 12 colors and start/end times (overnight and 24-hour shifts work)

■ Your data stays put
• Stored on your phone and included in Android backup and phone transfer

■ Pricing
• The core (rotations, month view, widget, totals, sharing) stays free. We will not move free features behind a paywall later.
• The free version shows ads. Orbiday Pro is a one-time purchase that removes ads and lets you keep extra schedules (your partner's or family's). No subscription.
