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.
