App for health professionals to exchange duty with colleagues from the same team in 3 different ways:
- Asking for replacement so that someone in the group is interested;
- Passing on duty to someone specifically on your team;
- Changing a shift as long as you get one back

Besides that:
- Manage your schedule and be reminded of personal commitments when volunteering for a shift
- See who is on duty on the scales of the teams you are part of
- View reports of hours worked or planned
- Communicate your arrival and departure by checking in / out via QRCode or GPS
