FretBored vs DeepFocus Study

You know what notes sound like. You just can't find them fast enough. FretBored fixes that. It plays a sequence of notes, you play them back on your real guitar, and the app listens through your mic to score your accuracy and timing. It's ear training that actually feels like a game with combos, XP, daily streaks, and a structured curriculum that takes you from open strings to full-neck fluency across all 12 frets. No guitar handy? Half the modes work without one. PLAY WITH YOUR GUITAR Free Play — Hear a sequence, play it back. Difficulty adapts to how well you're actually doing, not just how long you've played. Curriculum — 12 modules, 55+ lessons. Start with telling high notes from low ones. End with blind challenges across all 12 frets. Scale Practice — 20+ scales in open position and higher positions (5th, 7th, 12th fret). The fretboard adapts to show only the range you need. Lick Library — 16 real musical phrases across blues, rock, folk, and jazz. Learn actual music, not just exercises. Interval Training — Hear two notes, name the distance. Three difficulty levels.
