The app is free. Level 1 in full, with unlimited sessions, and training that adapts to your ear from the very first answer. You hear two notes. Which one is higher? By how much? And played together, could you name them? Recognizing intervals by ear is what separates the musician who reads notes from the one who hears music. It is not a gift, it is practice. And you do not need to read sheet music to start. TRAINING THAT ADAPTS TO YOU The ZDP engine reads your answers as you go and sets every exercise to the level you are at today. On a good run? Difficulty rises. An interval that keeps slipping? It eases off until that one sinks in. You stay where progress actually happens: never bored, never stuck against a wall. A DEBRIEF AFTER EVERY SESSION Apple Intelligence can analyze your work right on your device and give you personal feedback: what is settling in, what still needs time. Nothing leaves your device. FREE, FOREVER • All of Level 1, with unlimited sessions • The full adaptive engine within that scope • Your progress, your calendar and your stats • Reminders to help you keep the rhythm WHAT THE SINGLE PURCHASE UNLOCKS • Every level, from your first steps to the most demanding • The complete range of intervals, simple and compound, ascending, descending and harmonic • Your choice of which intervals to work on • The pathway built for the L.U.C.I.D. method One purchase, no subscription. FOR HOME AND FOR THE CLASSROOM Up to 3 independent profiles on a single device: everyone keeps their own progress, stats and pace. BUILT TO BE USABLE BY EVERYONE VoiceOver, high contrast, a dark interface, and feedback that never relies on color alone: every answer is marked by a symbol and by haptic feedback. Adapting properly means adapting to each person. YOUR DATA STAYS WITH YOU No collection, no account to create, no connection required, no permission to grant to get started. Everything happens on your device. Note Precision: Intervals accompanies the Relative Ear module of the L.U.C.I.D. platform, which grew out of a music teacher's work, and it fits practice with your teacher as naturally as working on your own at home. Available in 12 languages, as a native app on iPhone, iPad and Mac. This is the first app in the NotePrecision suite. The ear can be trained.

Hark trains your ear the way musicians actually hear: every note as a degree of the key, not a distance from the note before it. A cadence — or a drone — puts the tonic in your ear. A note sounds. You answer on a ladder of degrees, with the home note at the bottom like the ground. Then the note walks home, step by step, back to the tonic, so you hear the pull instead of reading about it. That walk is the explanation. There is no lecture. FOUR KINDS OF TRAINING • Degrees — one note at a time, from two degrees up to all twelve • Melodies — short phrases, name every note in order • Chords in the key — I, IV, V and the rest, heard by function • Progressions — three and four chords in a row INSIDE • A ladder of seven colours: tonic gold, dominant blue, leading tone red • Notes on a staff, spelled the way the key spells them • The walk home after every answer • Hands-free: train with the screen off, on a walk or in the car. The key, the note, a pause for your answer, then the answer spoken aloud. • Explore: hold any degree in any key and listen. No score, no history. • Five instruments: piano, guitar, strings, choir, electric piano • Your map: accuracy by degree and by chord, and what your ear mixes up • Ten languages, and a ladder labelled with numbers, movable-do syllables or note names — Do–Si, Do–Ti, H and B where they belong FREE, FOR GOOD Five degree levels in C major — up to all seven degrees across two octaves — two melody levels, two chord levels, the first progression level, hands-free training, the staff, a week of statistics, and all of Explore: every degree in every key, there to listen to. No daily cap, no timers. HARK PRO — MONTHLY, YEARLY OR ONCE Training in all twelve keys, chromatic degrees, minor keys, three octaves, all seven chords with sevenths, progressions, melodies up to five notes, custom drills, and the full map of your ear with four weeks of history.

NO ACCOUNT, NO ADS No sign-up, no ads, no streaks and no nagging. Your individual answers and detailed training history stay on your device.

Verdict

The call

The clearest difference is in-app purchases: Note Precision at none against Hark's 1. Note Precision also leads on device support (3 vs 1). Hark's advantage is update cadence (every 4 days vs monthly) and iOS requirement (17.0 vs 26.0). On price, review sentiment and ads there is nothing between them.
