The calendar has several view modes, and you can switch between them at any time.
Day view / week view
Tap the view button (the three dots in the corner) and choose "Week view" or "Day view". The week shows you all the working days at once.
Viewing several employees
Tap the employee button in the header and select several employees. The calendar automatically switches to a grid with one column per employee — handy when you want to see the whole salon at a glance.
Missed and canceled appointments
From the same view menu you can show or hide missed and canceled appointments.
Note: you can adjust how many days appear in the week view from Settings → Interface and language.
