Fret Flow

Train your ear and learn every note on your guitar. Fret Flow turns fretboard mastery into a focused daily habit. Instead of rote memorization, it uses spaced repetition and guided drills to build genuine recognition, so the notes become second nature under your fingers. Just plug in your headphones or let your device listen. Fret Flow hears your guitar through the microphone and gives instant, accurate feedback on every note you play. No MIDI adapter, no cables, no setup. Whether you're a beginner getting comfortable with the open strings or an intermediate player finally filling in the gaps on the higher frets, Fret Flow meets you where you are and adapts as you improve. FEATURES • Real-time pitch detection — play your actual guitar, acoustic or electric • Adaptive spaced repetition that zeros in on the notes you struggle with • Ear training drills to sharpen your musical instincts • Short, focused sessions designed to fit into any practice routine • Clean, distraction-free interface built for deep focus • All progress stored locally — no account, no sign-up • No ads. No subscriptions. No data collection. Ever. Practice a few minutes a day and watch the fretboard stop feeling like a maze.
