Description
ReFret makes fretboard memorization genuinely fun. Unlike dry exercises or flashcards, this is an engaging game that you'll actually want to play. Best of all, you don't need your guitar — practice anywhere you have a spare moment, whether you're waiting in line, on a break, or relaxing at home. The bite-sized rounds fit perfectly into your schedule, letting you build skills gradually without pressure.
All premium features are unlockable by earning ReFret dollars through gameplay — no real money purchases required. Fully customize your practice by concentrating on any fret range for as long as necessary, tailoring the difficulty to your current skill level. ReFret's consistent representation of sharps and flats using piano key conventions provides excellent memory aids for learning which frets contain accidentals. Unlike most fret memory apps that overwhelm you with too many possible wrong answers, ReFret Maestro streamlines the process: you only see two choices at a time — one correct, one incorrect — keeping you focused and making steady progress.
TWO GAME MODES
Beginner Console — Perfect for building foundational skills
Six answer buttons, one per string, each showing a note name
Tap the correct note for the highlighted string
Notes are revealed progressively before each round begins
Builds confidence with clear visual feedback
Maestro Console — For serious players who demand precision
No note names shown — pure memorization challenge
Advanced gameplay with streak tracking and multipliers
2x multiplier at 25 correct answers, 3x at 50
Rolling 60-segment streak meter for motivation
KEY FEATURES
Comprehensive Neck Coverage — Learn notes from open strings to fret 19 across all six strings
Customizable Experience — Choose from Classic, Tweed, and Maple console skins
Flexible Learning — Set starting fret, repetitions, direction, and progression to match your skill level
Virtual Currency System — Earn points through gameplay to unlock premium features like High Frets (12+) and Landscape mode
Optimized for All Devices — Clean, intuitive interface designed for iPhone
PERFECT FOR
Guitar students learning note positions
Players wanting to break out of "box patterns"
Teachers looking for a practice tool for students
Anyone wanting to master the fretboard once and for all
Stop guessing notes. Start knowing them. Download ReFret and transform your guitar playing today.
