輪班油人 is a mobile application developed by 水蛙工作室 specifically for employees of Taiwan CPC Corporation. It aims to provide a quick and convenient way for CPC Corporation shift workers and their families to access their shift schedules on their smartphones. The app converts the paper-based shift schedules into a calendar format, allowing users to easily view and keep track of their shifts.

With support for various CPC Corporation plants such as Dali, Kaohsiung, Taoyuan, Lin Yuan, and Chiayi, users can customize the displayed shift text and also view lunar dates and national holidays. It's important to note that this app is exclusively designed for CPC Corporation employees and may not be suitable for shift workers from other companies.
