This app is fairly limited, but it does exactly what they say it does. You can easily build a schedule layout for your type of shift work and keep track of it. Its the only app that I know of that will let you do this. Its also very easy to use! Id like to see more compatibility with other apps and devices in the future. Maybe something to allow your schedule to be transferred to the IOS calendar, or to allow the apps calendar to be read by amazon echo. Either way, if you work public service and have any type of rotating shift schedule, this app is perfect for building a long term outline of your work schedule!
