You hear the note.
Hark gives it a name.

Ear training by degree: every note heard inside the key, the way musicians actually hear.

Tap a rung. It sounds, then it walks home to Do, one step at a time — what the app does after every answer, instead of explaining in words.

A third above what?

Interval training teaches distances between two notes. Music does not move in distances — it moves around a home note that pulls everything back. That is why people who can name every interval still cannot name what they just heard in a song.

“A major third.”

Interval training. True, and useless the moment the first note changes.

“Mi — settled and bright, the note that makes the key major.”

Hark. The same sound, named by where it sits and where it pulls.

A cadence or a drone sets the tonic. A note sounds. You answer on the ladder. Then the note steps home to Do and you hear the pull rather than read about it.

What training looks like

A session: the answered degree fills with its own colour, the note sits on the staff, the ladder shows La.
Single degrees, from Do and Sol to all twelve. The staff spells the note the way the key spells it.
The walk home: Fa answered, and Do lights up gold at the bottom of the ladder.
Every answer walks home. The rungs light in time with the sound, down to the tonic.
Home screen with the map of the ear: seven degrees, each with its own colour and accuracy.
Your map: accuracy by degree and chord, and the pairs your ear mixes up.
Hands-free training: a large answer, Ti, and a timer, designed to be listened to rather than watched.
Hands-free: the phone in your pocket, the answer spoken aloud, on a walk or in the car.
Explore: the full ladder in C major, Mi held down and sounding, with its character below.
Explore: hold any degree in any key and just listen. No score, no history.

Melodies and chords in the key use the same ladder — short phrases to name in order, and I, IV, V and the rest heard by function rather than by shape.

I bought Hark Pro and it is not there

Open Settings and tap Restore purchases. Pro is tied to the Apple ID that bought it, so check the device is signed in with that one. If it still does not appear, write and include the purchase date.

Training with the screen off

Tap Hands-free on the home screen, or the headphone icon beside any level. Hark plays the key, then a note, waits for you, and says the answer aloud. Lock the phone and keep walking — the headphone buttons pause and skip.

The sound plays on silent

On purpose. An ear trainer that obeys the silent switch is a broken ear trainer. The instruments are real samples (FluidR3, CC BY 3.0); attribution and links are in Settings, under About.

Languages

English, Russian, German, French, Spanish, Italian, Brazilian Portuguese, Japanese, Simplified Chinese and Korean — with the syllables and note letters each one actually uses: Si rather than Ti in the Romance languages and Russian, H and B in German.
