PostalCal is a utility app designed specifically for postal employees who have rotating days off. It provides a straightforward calendar that highlights every payday and postal observed holiday, making it easier for users to keep track of their schedules.

Additionally, PostalCal includes in-app purchases that allow users to customize the color rotation of their calendar, adding a personal touch. Users can also enhance their experience by adding custom events, ensuring that all important dates are easily accessible. This app aims to streamline the scheduling process for postal workers and their families, making it a valuable tool for effective time management.
