Fret

Fret이란?

Most guitar learning keeps theory separate from the instrument. Fret puts it back on the neck. Pick a lesson → a backing loop starts → every scale-safe note lights up on the fretboard. Mic input detects when you hit them. Earn stars by landing on strong chord tones. Also has a free scale explorer: choose any scale in any key, see it mapped across the full neck, and let the mic match your playing to the closest scale in real time. Free. No download.
