FretChamp: Fretboard Trainer

FretChamp helps you learn your way around the guitar (and bass) fretboard — practice notes, chord tones, inversions, arpeggios and scales, with real-time feedback using your device's microphone.

Perfect for practicing anytime, even away from your instrument.

FEATURES
• Single Note — learn every note position on the fretboard
• Triads — find 3-note chord inversions
• 7th Chord — expand to 4-note inversions
• Tensions — add advanced chord colors
• Scales — practice scale shapes across the neck
• School — structured lessons that build your fundamentals step by step, from note-finding to chords, arpeggios and scales
• Tuner — a simple, accurate tuner to check your instrument is in tune

Every practice mode can use your device's microphone (Listen) to detect the notes and chords you actually play in real time — audio is processed entirely on your device and is never recorded or transmitted.

Switch between Guitar and Bass mode anytime with one tap — your choice is remembered for next time.

Please note: this app is not intended for teaching chord shapes — but the School section teaches the basics step by step, including open and barre chords, for both guitar and bass.


Have fun and good luck!
