Recognise intervals
Hear two notes melodically or harmonically and name their distance.
Training
Start an adaptive daily session or build a custom set around one skill. Both modes feed the same progress model, so every answer can improve what comes next.
App feature visualisation.
Eight focused exercises
Move from listening alone to placing and playing notes on your own instrument.
Hear two notes melodically or harmonically and name their distance.
Connect a note on the treble staff with its name and sound.
Identify the note at a highlighted string and fret.
Translate a sound into the exact place on your fretboard.
Locate one named note or every occurrence in a selected range.
Reveal octave patterns by marking all matching positions.
Find a requested interval above or below a starting note.
Study a note, hear it and play it back while local pitch detection guides you.
Adaptive planning
The generator balances four roles using your goal, level, instrument availability and skill history.
Familiar material brings your ear into the session.
Lower accuracy and mastery receive most of the attention.
Spaced-review timing brings back material before it fades.
A smaller share keeps your learning path moving forward.
Feedback that teaches
Replay sounds, reveal the answer on the fretboard and get guidance tailored to the task. In play-the-note exercises Fretuno distinguishes the wrong note, wrong octave and tuning drift.
Pitch is analysed on-device; raw microphone audio is never stored.
Continue manually or use a 1, 2 or 4 second auto-advance.
