App Description
Simple Work Calendar — your shift schedule in two taps. Pick a cycle, mark your first working day — the calendar computes all shifts and days off years ahead.
ANY SCHEDULE
• Ready cycles: 2/2, 3/3, 1 on / 3 off
• Custom patterns: any mix of working and off days — 5/2, 4/2, 6/1, 15/15 rotations
• Anchor the rotation to any start date — today, tomorrow or a day in the past
NIGHT SHIFTS
• Mark which shifts in the cycle are nights — shown in dark
• Tap any day to switch: day → night → off
• Manual edits never break the pattern
COUNTERS
• Working and off days per month or year, counted automatically
• Red dot marks today — always know where you are in the cycle
WHO IT'S FOR
Nurses, doctors, factory workers, security guards, drivers, retail staff, first responders — everyone who works shifts, not weekdays.
RELIABLE
• Your schedule is stored on the device and never disappears
• Works offline, no sign-up
• Setup takes under a minute
