What is a personal shift planner?

A personal shift planner helps workers organize early, late and night shifts, rotating schedules and days off. When working times change throughout the week, a digital shift calendar can be easier to maintain than a paper diary or a spreadsheet.

Shift Lion lets you save your own repeating rotation and plan work, leave, appointments and free time in one place.

What can you do with Shift Lion?

Plan every shift type

Create early, late, night and custom shifts with your own names, abbreviations, colors and working times.

Build custom rotations

Set up repeating shift patterns and choose an individual start date for each rotation.

Manage multiple groups

Keep several shift groups and different rotation systems visible at the same time.

Track leave and days off

Add vacation, free days and personal changes directly to your shift calendar.

Organize appointments

Place personal, work-related and repeating appointments beside your scheduled shifts.

Compare schedules

Compare shift groups and find shared days off with your partner, friends or colleagues.

Review statistics

Review planned hours

Use stored shift times to understand your planned working time.

Estimate pay and premiums

Use your shifts and settings for a non-binding estimate. Results are not payroll, tax, legal or financial advice.

Export your calendar

Use iCal for Google Calendar and compatible calendar apps, or create a PDF overview.

Back up locally

Create a local backup and restore your personal planning data when needed.

Use it offline

Plan locally without mandatory registration, advertising or a cloud requirement.

Shift planner, employer roster and time clock: the difference

Personal shift planner

Copy your own assigned shifts into a personal calendar and organize life around them.

Employer roster

Your employer remains responsible for assigning staff and publishing the official roster. Shift Lion does not replace workforce-management software.

Not a live time clock

Shift Lion evaluates planned times stored with your shifts. It is not a clock-in and clock-out attendance system.

Real views from the English version show how schedule comparison, statistics, pay estimates and local backup work together.
