Note Blaster now hears you play. Point your phone at your guitar, pluck the note on screen, and it fires — detected from the real sound of your guitar, not a button tap. Can't get to your instrument? Tap the fretboard instead — both ways always work. You have three lives and must destroy 30 notes per level. Miss too many and it's game over. Note Blaster teaches the notes of the guitar one string at a time, starting with the 1st string (E, F, G) and working across the fretboard until you know it all — while blowing up notes to a bluesy backing track. FEATURES: • NEW — Mic mode: play real notes on a real guitar, the app hears you • Acoustic mode for quiet, unplugged guitars in noisy rooms • Learn step by step, one string at a time • Practice area to study notes before you play • Three difficulty modes: Easy, Intermediate, and Hard • Session Mode — a teacher picks the notes, a student plays a mini-game, results save automatically (built for guitar teachers and their students) • Note Movement — choose Step, Step & Leap, or free Random note order for interval training within a session • Session Scoreboard — every student's practice history at a glance, including which note-movement mode was used • Local high score leaderboard Whether you're teaching yourself or teaching a room full of students, Note Blaster turns learning the fretboard into something you actually want to play. MORE FROM GUITAR EDUCATION • Note Master — read notes on the stave in one minute. • Minute Chords — build clean chord changes against the clock. • Piano Note Blast — learn the notes on the piano. • TunerGed — fast, accurate tuning for guitar and more. • Metro Step — metronome and tempo trainer. Built by a working guitar teacher, for the practice room. gerardgrundy@guitareducation.com
