Company profile
researched Aug 2026MYDUTY is a shift-work calendar and alarm application aimed at nurses and hospital staff managers. Users create, manage and track duty schedules in a dedicated calendar, set alarms tied to individual shifts, view schedules through a home-screen widget, and track vacation days. The app supports groups: members can be invited to a shared group where all participants' schedules are visible at a glance, and each group has a private notice board for discussion. Schedules can also be shared outside the app as an image of the calendar (showing duties while hiding personal events) or as a web link that remains valid for ten days and can be revoked from the sharing menu.
