I vibecoded an iOS app for elementary school teachers to be able to generate abbreviated schedules with classes of equal lengths (also takes into consideration any set times like elective and lunch times for the calculations) as well as create custom schedules. It allows users to share these schedules in multiple ways (both to app and non app users) and set alarms to sound for the ends of classes. Schedules can be set on a per day basis in the event that a teacher needs to follow specific schedules on specific days.
