Shivox Shift Calendar

Shivox Shift Calendar is a straightforward tool for workers who need to track rotating shift schedules without the clutter of a full-featured calendar app.

You can define named shift types, assign each one a distinct color, and map them onto a repeating cycle of any length. Once a pattern is set up, the calendar fills in automatically so you can see your upcoming rotation at a glance.

Each day on the calendar shows the assigned shift color, making it easy to spot your workdays, days off, and different shift types without reading any labels.

The app works entirely offline. There is no account, no sync, no server. Everything you enter is stored locally on your device.

Settings include a choice of four visual themes — two light and two dark — adjustable font size, and the option to start the week on Monday or Sunday. All preferences take effect immediately across the whole app.

Designed for shift workers who want something simple, reliable, and private.
