You want to improvise without thinking about it. Not scales. Not the licks you already own. The line you actually hear, played the moment you hear it. Your ear is not what is stopping you. You can hear where the phrase wants to go. What stops you is the half second in between: the one where you work out that the note you want is the flat three, while the chord underneath has already moved on. Fluency is not knowledge. It is speed. And speed only comes from repeating exactly the right thing, thousands of times. That is all Improvy is. A degree appears, you tap the note. Two seconds. Again. Until the number, the sound and the note stop being three thoughts and become one. It works in all 12 major keys, and it spells every one of them the way a musician actually writes it. In Eb the flat two is Fb, not E. Most apps quietly get that wrong, and the habit you build on top of it is wrong too. Train it in both directions, because they are two different skills. Number to note. Note to number. Then the one that turns a melody into changes: this note is the sharp eleven, so what is the chord? There is a Daily Challenge every morning, and Pocket Mode runs with the screen off, so a walk counts as practice. This is not for beginners. It is for players who already know the theory and are tired of being a beat behind it. No ads. No account. Pro is a one-time payment. Stop counting. Start playing!
