A schedule that looks efficient on paper can quietly run a teacher through lunch and past a legal day. Set the Tune builds the workday rules into the engine, so the schedule it produces is one a person can actually work.
Set the Tune holds each teacher to an 8-hour day and counts driving between homes as paid work toward that cap, because it is. When a day would run long without a break, the engine forces a real 30-minute meal break before the worked clock crosses the line, and a second one before a very long day.
Import the roster you already have and Set the Tune places every student in one pass. The optimizer respects each family’s availability windows, matches students to the right teacher and instrument, never double-books, and keeps each teacher inside a real workday.
It is deterministic and free to run. Press the button again after a change and it converges, it does not reshuffle a schedule that is already good.
Every lesson is checked the moment it lands. Double-bookings, availability violations, teacher overload, and travel that is physically impossible all surface as flags you can see, not surprises a parent finds for you.
