Drop2: Jazz Guitar Ear Trainer — your complete practice coach
Drop2 listens to your playing through the microphone and gives you instant, note-by-note feedback: no cables, no interface, just your guitar and your phone. It even hears you over its own backing band: play along over the speaker, no headphones required. A smart scheduler points your practice at what you haven't nailed yet. No guitar to hand? Tap the neck instead, or train your ear alone.
Works with acoustic and electric guitar. All listening happens on-device. Your playing never leaves your phone. Designed for iPhone and iPad.
FRETBOARD TRAINER
Hear a note, then find and play it anywhere on the neck. Start with naturals, add sharps and flats, then the whole fretboard. Spaced repetition drills the positions you keep missing.
PRACTISE WITHOUT A GUITAR
Guitar in the other room? Tap the answers instead. The app names a note and a string and you find it on the neck; it names a chord and the voice on top and you build the grip with four taps. Same material, same scheduler, no microphone and no permission.
SCALES & ARPEGGIOS
Play the one-octave scale or arpeggio for any root and chord quality — m7, 7, maj7, m7b5, dim7, mMaj7 — and have each note checked by ear. A full-neck map colors the chord tones and degrees so you see the shape as you learn it. A built-in curriculum opens new keys and qualities as you master the basics.
LINES — SOLO OVER THE CHANGES
Walking bass and drums loop a progression or standard form — ii–V, the blues, the bird blues, rhythm changes, the Coltrane cycle, Take the A Train, So What, Blue Bossa, Autumn Leaves, All the Things You Are, and more — while you improvise. Targets mode prescribes the guide tone to land each bar and grades your voice-leading. Free mode classifies every note live — chord tone, tension, avoid or outside — on a color-coded neck map. Score on headphones or over the speaker: an on-device model picks your guitar out of the band.
DROP-2 VOICINGS
Learn and drill the essential jazz voicings across roots, qualities, inversions, and string sets. Browse any shape, hear it strummed, read its intervals — then quiz yourself: the app names a chord, you play it, and all four notes are scored, octave by octave, so it tells inversions apart. Includes ii–V progressions, a daily review, and a play-along band to comp the changes with.
EAR TRAINER
No guitar, no mic — pure listening. Drop2 plays an interval, a chord, a cadence or a phrase, and you answer on the neck: intervals as degree-labelled circles, chords as real drop-2 voicings in any inversion — name the quality, or the voice on top — cadences as voice-led shapes that step across the neck as they sound, and jazz phrases you tap back note by note. Hold any answer to hear it first.
PRACTICE THAT ADDS UP
Every drill has a finish line: a run of questions, a strip that fills as you answer, and a result card with your score and your personal best. Tell the app how long you have and whether you have a guitar, and it plans the day's workout — an ordered route across the trainers that hands you on as each step is done. Behind it: current and best streak, an activity heatmap, accuracy trends, and coverage grids. It syncs across devices with iCloud — your plan, your bests and today's practice, not just the log — with a JSON backup you control. A widget puts your streak and your next step one tap away, plus an optional daily reminder.
