The Whole Horn
If a letter tells you something about this app, you should be able to read what stands behind it. Each claim is below — what it means, why it is true, and how to check it without taking my word for anything.
There is nothing to configure before you use it. No class to create, no roster to import, no seat licences to count, no student to enrol, and no password anyone can forget. You open the app and it works; a student opens the app and it works.
This is not a setup process that has been made fast. There is no setup process. The app has no concept of a class, so there is nothing for it to know about yours.
The app gathers no student names, no email addresses, no logins, no location, and no analytics. It has no server to send anything to. Everything a student does stays on their own device.
You do not have to take that from me. Apple requires every developer to declare what an app collects, and publishes the answer on the store listing itself. The Whole Horn's reads Data Not Collected — a third party's statement, not mine.
What this does not mean is that your district's review is unnecessary; that is your district's call and their policy, not something I can decide for them. It means there is no personal data for that review to find.

Anything a teacher can assign is free, permanently. Not free for a term, not free during a trial — free, with no mechanism by which it could later stop being free.
This is a rule inside the app, not a promise in marketing copy. The material a practice link can carry is drawn from the free set, so a student who follows their teacher's assignment cannot arrive at a paywall. There is an optional one-time unlock for advanced material, and a teacher cannot assign into it even by accident.
The reason is simple. A teacher should never have to wonder whether tonight's homework is going to ask a family for money.
You call one key. In a mixed room that key is a different written key for nearly every chair — the trumpet reads one thing, the alto another, the horn another, the flute another again. Traditionally somebody writes all of that out.
Here, every player opens the same link, and each one sees the exercise in their own correct written key, in the right clef, inside a range their instrument can actually play. Sixty-nine instruments: the winds and brass, strings, voice, mallets — and timpani, notated across all twelve major scales in bass clef at the real range of a standard set of kettles, which most method books never bother to do.

The app keeps a log of what was actually practised — which exercise, how many repetitions, how many minutes, and when it was last done. That log lives on the student's own device.
They can export it as a CSV and send it to you if they want to. They are not obliged to, and nothing is sent anywhere automatically. It replaces "I practised, I promise" with something real, without turning a practice app into a surveillance tool pointed at a child.
A beginner is normally asked to learn four separate skills, separately: read the note, work out the rhythm, find the fingering, and listen well enough to play in tune. Taught in isolation, each one is a wall.
Here they arrive together. The student hears the pitch, watches the note move across the staff at the moment it sounds, feels the subdivision underneath it, and plays. Reading, rhythm, fingering and ear stop being four subjects and become one activity — which is how musicians actually learn, and how nobody ever learns from a fingering chart.
Range is a slider. A student in their first week who can play three notes practises three notes, and the written scale grows one note at a time as their embouchure allows.
This is the difference between a tool for the outlier who already wants more and a tool you can assign to a whole first-year class. It is both. The same engine serves a beginner managing three notes and a player warming up across the full range of the horn — only the slider moves.
A needle tells a student they are four cents flat. It does not teach them to hear it, and a student who learns to watch a needle has learned to watch a needle.
Instead, students play against sustained drones and hear the harmonic series — the beats, the moment a note locks in, the physical sensation of an interval settling. That is how intonation has always been taught in a room with a good teacher in it.
One of the ear-training games asks the student to sing back what they hear, and reads the pitch of their voice to show them how close they got.
That happens entirely on the device. Nothing is recorded, nothing is stored, and nothing is sent anywhere — the microphone is used in the moment and the sound is gone. It is the only part of the app that listens at all, and it listens to singing, never to a child's room.
There are no rewards, no leaderboards, no streak a student is afraid to break, and no notifications engineered to pull them back.
The argument for those things is that they drive engagement. They do. They also teach a young player to practise for the badge, and a student practising for a badge stops the day the badge stops mattering. The intent here is that the improvement is the reward, because that is the only one that lasts a career.
Most classroom software solves "give this assignment to those students" by building a roster: accounts, logins, a database somewhere holding children's names. That database is what triggers the IT review, the privacy paperwork, and the months of waiting.
Here, your settings — exercise, key, tempo, note values, range, articulation, hours, and your own written instructions — travel inside the link itself. There is no roster because there is nowhere to keep one, and no record of who opened it. The student is anonymous because there is no mechanism by which they could be known.
Every other practical advantage on this page follows from that one decision.
The staff you see is generated at the moment you look at it, for that instrument, that key, that range and that tempo. It is not a scan, not a PDF, and not a photograph of someone else's sheet music resized to fit.
Which is why it can be correct for sixty-nine different instruments without sixty-nine different files existing, and why it stays sharp on a phone, a tablet, or a printed page.
The foundation is free forever, with no advertising: all twelve major scales on every instrument, the metronome, long tones, vibrato, the Tuning Room and the ear-training games.
A single optional purchase of $24.99 — once, not monthly — adds the advanced method: minor scales, intervals, chords, chromatic technique, modes, overtones and twenty-two Arabic maqamat. There is no subscription and there never will be. If a student never spends a penny, they still have everything a teacher can assign them, for as long as they play.
