About this app

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.

START FREE, FOR AS LONG AS YOU LIKE
Level 1 is free and unlimited. No daily quota, no countdown, no ads. Practise as much as you want, for as long as you want. A single purchase unlocks everything else, and there is no subscription.

THE GUIDED L.U.C.I.D. PATH
Beyond free practice, a structured course takes you from your first ascending second to compound intervals, step by step, with your level assessed automatically and the next stage recommended for you.

IT ADAPTS TO WHOEVER USES IT
A curious beginner, a choir singer sharpening their ear, a music student working alongside their teacher, a child whose parent opens the app for them: everyone finds their level. Independent profiles keep each person's progress separate, so an app can be shared at home or in a music school.

That is also why accessibility got as much care as everything else: TalkBack support throughout, a high-contrast mode, and layouts that hold together at the largest font sizes. Adapting for real means adapting for everyone.

WHAT YOU WILL FIND

YOUR DATA STAYS ON YOUR DEVICE
Nothing is collected, nothing is sent anywhere. No account to create, no sign-in, no tracking. Your answers, your statistics and your profiles live in your phone and nowhere else.
