Shift Calendar (since 2013) のアプリ分析 10月4日

This app is designed for all hard-working shift workers. You can add customized shifts. 
When editing your shifts, you can select a range of days (rather than one day) to set. Thus, you can set your schedule (roster, planner) in few seconds. Then, you can send the screenshot of your calendar to friends by clicking one button. If you have any suggestion/question, welcome to send an email to me.
