Shift Calendar & Alarm

A clean, simple shift calendar designed for workers with irregular schedules.

If your days off change every week, a regular calendar won't cut it. Shift Calendar gives you a blank slate — add your shifts, and your calendar builds itself around your actual work life.

【KEY FEATURES】

◆ Shift Entry Made Easy

Tap any date to add a shift with start/end times, and optionally set a label and color. Cross-midnight shifts (e.g. 22:00–06:00) are fully supported.

Set a unique alarm for each shift. Wake up at 5:30 for early shifts, 13:00 for lates — no need for a separate alarm app. Alarms ring even when the app is closed.
