## What is FretBuilder?

Grow as a musician by visualizing notes on your instrument's fretboard. With this app, you can view some (or all) of your instrument's fretboard, tap to hear pitches at any string/fret, and use overlays to help you quickly identify pitches. The app supports multiple fretted string instruments, including guitar, bass guitar, and ukulele. It also features some of the most common preset tunings. Some advanced features of the app are enabled with a subscription, including custom fretboard designs (via photo library selection), custom instrument tunings, and a special overlay mode that lets you tap any position on the fretboard to see the individual pitch! More features are planned, so keep your eyes peeled and your instruments tuned!
