IOS6. If the app isnt able to access to device calendars, please go to device "Settings" -> "Privacy" ->"Calendars" and activate access to "Shifts"
Work Shifts is a handy application to manage your work shifts.
Work Shifts uses your device calendars data, so it automatically updates the information with any calendar registered on your device. So any change would be updated to MobileMe on the go (if you have a MobileMe account), with iCal as you connect the device to the computer, or even GoogleCalendar or other calendar service if you register one or many calendar accounts.
Easy month shifts input: one touch to program, or one touch to unprogram.
View all your month evens as an icon, or as 1 to 3 letters, (up to 4 evens a day)
Create a shift template using the data you have already got on your device.
Calculate the (working/holidays/other activities) hours of every month, as many groups as you like.
You can choose the text color for each event and the background color for each day.
