ShiftPattern is a work calendar for people whose schedule changes from week to week or follows a repeating rotation. It includes common patterns such as 4-on/4-off and 2-2-3, while allowing custom shifts and edits to individual days without rebuilding the whole cycle. Users can mark swaps, leave, overtime, breaks, and notes, then review hours by week, month, or pay period. Optional hourly-rate settings produce a simple earnings estimate, and the app includes reminders, widgets, sharing, and backup export. It is designed for tracking a personal roster; its pay figures are estimates rather than payroll calculations.
