Learn acoustic guitar five minutes a day — with a coach that actually listens. StrumBuddy uses your iPhone's mic to hear you play, then gives the kind of feedback a good teacher would: not just "right or wrong," but exactly which string buzzed, which note didn't ring, and which chord change is falling apart under tempo. Then it tells you the one thing to work on next. WHY STRUMBUDDY IS DIFFERENT • It listens. Play a real acoustic guitar — no tapping along to a screen. • Per-string feedback. See clean vs. muted vs. buzzing for every string, so you know precisely what to fix. • An adaptive coach. StrumBuddy tracks your individual skills, finds your weak spots, and shows its reasoning — "your C is fine; it's the change into it that needs work." • A 5-minute daily habit. One tap starts a short guided session that always ends on a win, with a streak to keep you going. WHAT'S INSIDE • Chord trainer with live, per-string cleanliness feedback • Chromatic tuner • Transition drills with a metronome to tighten your chord changes • A guided daily session picked for you by the coach • A skill path that grows as you do BUILT FOR BEGINNERS Most people who pick up a guitar quit within a few months. StrumBuddy is built to get you past that — small daily wins, clear next steps, and feedback that meets you where you are. PRIVATE BY DESIGN StrumBuddy processes audio on your device. No account, no tracking, nothing sent to a server. Grab your guitar and play. StrumBuddy is listening.
