This app is a management tool for streamlining monthly tuition management for classrooms and extracurricular activities. It allows parents and teachers to create monthly tuition plans for each group and automatically sends unpaid notices. Event and practice schedules can be easily shared using a calendar view, and attendance notifications can be sent with just one tap. Cashless payment eliminates the need for bank transfers or cash exchanges, helping to prevent issues. It also allows for the management of multiple children's information and plans, and the notification function prevents oversight.
