Shifter is a free app, developed for workplaces to manage a weekly shift routine.

Managers can create a weekly schedule of shifts for a group of employees, which will, later on, submit their preferences for each shift (whether they are available, not available, or prefer a certain shift).

Once the deadline for the employee's submission of preferences has reached, managers can then review each employee's preference, and assign shifts with consideration and ease.

All that is left to do is publish the schedule, and let the work begin!
