Note Precision: Intervals

New: the app is now free. Level 1 in full, with unlimited sessions, forever. A single purchase unlocks all the other levels, with no subscription.

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.
