Where the journey began

It started with Isaac’s piano lessons.

Which weeks were paid? What’s on next? Harmonic began as the answer for one family. Cindy, Isaac’s piano teacher, was the first teacher to use it, and helped test every version. Now it keeps every lesson straight, for any subject.

Scheduling

Set it once.
The term fills itself in.

The teacher adds a student’s lesson and makes it weekly. Every date appears for the teacher, the student and their family.

A lesson: when it starts and ends, that it repeats weekly, attendance and paymentA lesson: when it starts and ends, that it repeats weekly, attendance and payment

Attendance

One tap after class.
Attended, and a credit comes off.

The teacher marks it before the next student sits down. The balance stays right, with no spreadsheet.

Payments

Pay for a lesson.
It becomes a credit.

The teacher records it once. Teacher and student see the same balance, lesson by lesson.

Payments: credits, lessons attended, the balance, and a ledger of each entryPayments: credits, lessons attended, the balance, and a ledger of each entry

Notifications

Everyone hears.
Everyone linked, straight away.

Reschedule, mark attendance or record a payment, and the student and their family know the moment it happens.
