About this app

"Class Time for Teachers" is a simple time management app that allows teachers to "register a timetable and set a dedicated clock for the teacher,"
allowing teachers to understand the flow of their lessons at a glance.

By registering a timetable for each day of the week,
you can see the current class, next class, and remaining time on one screen.

No complicated settings or operations are required.
Just look at it or open it to tightly control class time.

This is the simplest timetable app for teachers who want to focus on their lessons.
Of course, it can also be used for all other needs.

"Class Time for Teachers" was created from the perspective of instructors who actually teach in the classroom.

We designed this app to eliminate that hassle by allowing teachers to see their class schedule, current period, and remaining time on a single screen.

The purpose of this app is to allow teachers to understand the current situation without any extraneous operations.
