■ What is the Monthly Tuition Envelope App?

This app is for independent teachers managing monthly tuition and lesson schedules.
It can be used for all types of lessons, including guitar, piano, yoga, and dance.

While retaining the benefits of paper monthly tuition envelopes, it digitizes them in a way that's easy for both teachers and students to use, eliminating the worry of losing them and the hassle of counting. Google Calendar integration also automates lesson schedule management.
