Stringflo helps guitarists build real fretboard fluency through interactive note training, real-time pitch detection, theory tools, tuning support, and visual progress tracking.

Practice with randomized note challenges, get instant feedback as you play, reveal fretboard positions when you need help, and customize your sessions by string, note, and sensitivity level. Then go deeper with built-in theory tools for chords, scales, CAGED shapes, intervals, fret numbers, and full-neck maps.
