Fretling Turns Guitar Theory Into a Fretboard Sentence

Why it surfaced

Its whole interface is built around a sentence such as “I want to learn scales in E Major,” with each colored word changing the lesson. The guide also documents chord identification, CAGED and 3NPS overlays, tap-to-hear notes, a tuner, metronome, looper, and amp tools, all presented with no account and no analytics.

Fretling is an offline guitar-learning app for Mac and iPad that uses plain-language controls to show scales, chords, triads, and practice patterns on an interactive fretboard.
