ChordDeck is a compact flashcard app for practicing jazz chord recall. Choose the roots and chord qualities you want to drill, then move through a focused deck one card at a time. Each card starts with a chord symbol so you can recall the answer mentally or on your instrument before revealing the details. Reveal a card to check the chord tones, a short formula, a compact piano keyboard highlight, and built-in audio playback. Mark difficult cards during practice and review them again later from the first screen. ChordDeck is designed for musicians who already know basic chord concepts and want a fast, repeatable way to build fluency. It keeps practice visual and direct instead of turning each session into a lesson page. Features: - Practice common jazz chord qualities across selected roots. - Follow circle-of-fourths root order or use random card order. - Choose one-pass sessions or continuous practice. - Reveal chord tones, formulas, and compact keyboard highlights. - Hear chord tones followed by the full chord. - Mark difficult cards and review them in a focused deck. - Use swipe navigation, previous and next controls, and timed autoplay. - Keep practice settings and marked cards stored locally on your device. ChordDeck is useful for jazz students, pianists, guitarists, bassists, arrangers, and other musicians who want quicker recognition of chord symbols, tones, and formulas.

Most guitar apps show you one scale or arpeggio at a time. KnowYourNeck shows you how everything connects. WHAT MAKES IT DIFFERENT • Multi Arp — Overlay up to three arpeggios simultaneously. See the chord tones for an entire progression on the neck at once, so you can practice connecting lines and navigating changes instead of just memorizing isolated shapes. • Target Notes — Identify which notes are safe landing points between chord changes. Overlaying a scale against an arpeggio shows you exactly which degrees work as target notes when you land on a new chord — the key to sounding musical instead of mechanical. • Play Along with Visual Overlay — Practice with backing tracks while the fretboard changes with every chord in your progression. A preview shows the upcoming scale or arpeggio before the change hits, so you can prepare your line in advance. Available in Jazz, Blues, Rock, Funk, Bossa, and Drone styles. EVERYTHING ELSE YOU GET • Intervals — Visualize the distance between any two notes across all six strings. • Scales — Every common scale and mode mapped across the full neck with color-coded degrees. • Chords — Triads, Drop 2, Drop 3, and Shell voicings with every inversion drawn as a grip across the neck. • Lick Builder (Pro) — Tap out note sequences on the fretboard and save your lines. • Quiz Mode (Pro) — Test intervals, chord tones, and scale mastery with detailed accuracy and speed stats. • Pitch Detection — Play a note and the app identifies it on the neck in real time. • Zen Mode — Full-screen fretboard with no chrome, for focused practice. BUILT FOR LEARNING Toggle note names or scale degrees. Switch sharps and flats. Show or hide open strings. Chromatic color mode to spot patterns fast. Whether you're working on your first pentatonic or learning to navigate a jazz progression, KnowYourNeck shows you the neck the way it actually works — as a connected system, not a collection of boxes. Free to explore. Upgrade to Pro for the Lick Builder, Quiz Mode, and Play Along.
