Three classroom recipes

5-minute warm-up

Start the lesson in Practice mode: each student walks one string, saying the note names out loud before playing them on the violin.

The Daily challenge as homework

Every student gets the same sequence of notes, so results are comparable at a glance, and streaks keep the habit alive between lessons.

A monthly fluency check

Once a month, have each student set a record in Infinite mode and write it down. Watching that number grow motivates more than any grade.

What you can measure

The stats screen keeps overall and per-note accuracy, streaks and achievements, stored on the student's device and ready to show you in class.

Questions from teachers

Do my students need an account?

No. They open the web app and play; progress is saved on their device. Nothing to register, no passwords to forget.

Does it collect data from minors?

It collects no data from anyone: there are no servers and no analytics. Everything stays on the student's device.

Does it work on classroom tablets and computers?

Yes, any modern browser. It can be installed like an app and keeps working offline once loaded.

What ages is it for?

Any student learning to read the treble clef: children with basic reading, teenagers and adults. You choose which notes appear and how fast.

How do I see a student's progress?

Ask for their stats screen, or for their Daily-challenge result: it is the same challenge for everyone, so it is a fair day-to-day comparison.
