Store listing
By CroCro, from Google Play“One app for tuner, chords, scales, jazz backing, pedalboard & score editor”
Description by CroCro Written by the developer, not by AppBrain. Click to read.
Fast, accurate chromatic tuner. Flexible metronome with subdivisions. A built-in drum machine and jazz/rock backing tracks to practice your timing, groove and licks.
● CHORDS, SCALES & FRETBOARD
Explore chords, scales, modes and arpeggios across the whole neck. See positions, inversions and voicings. Get scale and mode suggestions for any chord or progression — perfect for improvisation.
● JAZZ, DONE RIGHT
Real jazz content most apps skip: ii-V-I progressions, turnarounds, reharmonization, tritone substitution, modes and voice-leading. Play over jazz backing tracks with the right scales suggested for each chord.
● INTERACTIVE MUSIC THEORY
A theory course you HEAR, not just read — from the harmonic series to secondary dominants and voice-leading, with listening and hands-on manipulation built in. Ear training to recognize intervals, chords and progressions by
ear.
● PEDALBOARD & LOOPER
A real low-latency guitar pedalboard: overdrive, distortion, delay, reverb, chorus, amp and cabinet simulation, plus a looper to build and practice ideas.
● SCORE EDITOR + MusicXML
Write, read and edit scores and tablature. Import and export MusicXML to work with MuseScore and Guitar Pro — your work stays open, not locked in a closed format.
● SCAN A CHORD CHART FROM A PHOTO
Turn a paper chord chart into a digital one with your camera. Processed entirely on-device — nothing is uploaded.
WHO IT’S FOR
Intermediate to advanced guitarists, self-taught players formalizing their theory, jazz students working through standards, and anyone who wants tuning, practice, sight-reading and composition consolidated into one app.
