Note Precision: Intervals

You hear two notes. Which one is higher? By how much? And played together, would you recognize them?

Recognizing intervals by ear is what separates the musician who reads notes from the one who hears music. Good news: it isn't a gift, it's practice. And that's exactly what this app is for.

Its ZDP engine reads your answers as you go and sets each exercise to your level right now. A good streak? Difficulty climbs. An interval giving you trouble? It eases off until that one clicks. You stay where real progress happens: never bored, never stuck against a wall.

At the end of each session, Apple Intelligence can review your work right on your device and hand you personalized feedback: what's settling in, what still needs time. And nothing leaves your phone.

It also adapts to whoever's using it. A curious beginner, a choir singer sharpening their ear, a child whose parent or teacher opens the app for them: everyone finds their level. That's why accessibility got as much care as everything else: VoiceOver, high contrast, large text. Adapting for real means adapting for everyone.

What you'll find:
• Every interval, from simple to compound, ascending, descending and harmonic
• Difficulty that adjusts to each answer, no fixed tiers
• Your progress tracked over time, exercise after exercise
• Multiple independent profiles, to share with family or students
• Available in 12 languages
• iPhone, iPad and Mac, native on each

One purchase, no subscription. The price of a single private music lesson, for unlimited use. And your data never leaves your device.

Note Precision: Intervals works just as well with your teacher as on your own at home. It's the first app in the NotePrecision suite.
