FretFlo vs MetroCore

Find a better way to play it. FretFlo helps guitarists turn chord progressions into playable voicings that work together across the fretboard. Enter your progression, choose where you want to play on the neck, and FretFlo generates two carefully selected paths through the chords. Instead of looking at each chord in isolation, FretFlo considers the progression as a whole—helping you find parts with natural voice leading, comfortable movement, and voicings that fit together musically. Whether you're working out a second guitar part at rehearsal, exploring new ways to play a familiar progression, or trying to move beyond the same open chord shapes, FretFlo gets you from chords to playing quickly. GENERATE BETTER VOICINGS Enter a progression and get playable chord shapes selected to work together—not just a list of every possible fingering. EXPLORE TWO MUSICAL PATHS Compare two different approaches to the same progression and choose the one that fits your part. CHOOSE YOUR POSITION Point FretFlo toward the area of the neck where you want to play. It's a musical starting point, not a rigid boundary, so the progression can move when a better voicing calls for it.
