If you and your partner work shifts, you can use MyShiftPlanner to see each other’s patterns.
Either use Live Sharing or add a second calendar and overlay the two to see your shift rotas together.
To add another calendar:-
-Tap on Calendars at the bottom of the screen
-Alternatively, Swipe up on the Screen
-This brings up the Personal Calendar Menu. From here you can set up a new calendar or choose to overlay two calendars onto each other.
There is currently no limit to the number of calendars you can add.
