Trains notes in a key Whether you identify what you hear relative to a tonal centre, or as an isolated distance between two notes. This is the difference between an ear that works on real music and one that only works on quizzes. | ✓YesEvery mode establishes a key first, then asks what you heard inside it, labelled as scale degrees or solfège. | ✓YesThe cadence-then-scale-degree exercise is its entire design. | ~PartialIncludes functional and scale-degree work, but much of the syllabus is abstract interval and chord-quality identification. | ✕Not foundInterval and chord drills are presented without a key centre. | ~PartialIncludes solfège and some in-key work, but the core drills are abstract. | ~PartialSome in-key games, but most identify intervals and chords in the abstract. |

Trains chords by function Whether chords are drilled by their role in a key (the 4, the 5, the 6) rather than only by quality (major, minor, diminished). Function is what you need to hear a progression. | ✓YesChords are drilled as Nashville numbers — the 1, 4, 5, 6, then the 2, 3 and 7 — with inversions and non-diatonic chords unlocking later. | ✕Not foundSingle notes only. | ~PartialExtensive chord identification, mostly by quality and inversion rather than by role in a key. | ~PartialChord identification by quality and inversion, not by role in a key. | ~PartialChord identification by quality; progressions can be built manually. | ~PartialChord and progression games, mostly by quality. |

Trains hearing inside a chord Whether you practise picking out individual notes within a sounding chord — the skill behind transcribing voicings, harmonising, and singing a part. | ✓YesA dedicated Harmony mode plays a chord and asks which note inside it you heard, including complex chords. | ✕Not foundNo chord-tone identification. | ~PartialChord and progression dictation, rather than picking a single note out of a sounding chord. | ✕Not foundNo chord-tone identification. | ✕Not foundNo dedicated chord-tone identification mode. | ~PartialChord-tone games exist alongside a broad mixing-ear syllabus. |

Trains intonation in cents Whether you practise hearing that a note is slightly sharp or flat. Naming intervals is a labelling skill; hearing tuning is a resolution skill, and they train separately. | ✓YesA dedicated Intonation mode asks whether a note is in tune, tightening from 15 cents to 5 cents as you improve. | ✕Not foundNo tuning or cents work. | ✕Not foundNo cents-level tuning drills. | ✕Not foundNo cents-level tuning drills. | ~PartialMicrophone singing exercises; no cents-level tuning discrimination found. | ✕Not foundNo cents-level tuning drills. |

Removes crutches on a schedule Whether difficulty escalates on its own — dropping the reference note, adding inversions, widening the range — rather than leaving you to pick settings you are already comfortable with. | ✓YesLevels unlock a second octave, inversions, complex chords and extra scale degrees, and take the reference note away at level 3. | ✓YesLevels widen from part of a scale to multiple octaves. | ✓YesGuided courses set the order and the difficulty. | ✕Not foundEvery exercise is manually configured; nothing escalates on its own. | ~PartialStructured units exist, but difficulty is mostly yours to set. | ✓YesThe daily workout picks the games and the level for you. |

Built around a daily habit Ear training is decided by how many days you show up, not by how much content the app has. Whether the app is shaped like something you open every day. | ✓YesRounds run about a minute, with three lives, a combo multiplier and optional daily reminders. | ~PartialStructured drills, but no game loop pulling you back. | ✕Not foundDesigned as study software for longer sittings. | ~PartialChallenge Mode adds a timer and a personal high score. | ~PartialPractice reminders, but no game loop. | ✓YesA five-game daily workout is the centre of the product. |

Leaderboards Whether progress is visible against other people, which is what keeps a practice habit alive past the first fortnight. | ✓YesGlobal leaderboards and shareable scores. | ✕Not foundNo leaderboards. | ✕Not foundNo leaderboards. | ✕Not foundScores are private to you. | ✕Not foundNo leaderboards. | ✓YesWeekly contests, a performance index and a large community. |
