This is the natural progression from the Chord Solver website. I considered what I had made with the Chord Solver website and decided that I wanted to create an app that added new features. Using Swift and SwiftUI, I created this app with three primary functions: the interval solver, scale builder, and chord solver. The interval solver is similar to what the website already does, however, the scale builder and chord solver, offer two new tools that offer even more help with music theory. All you have to do is type in one note, and the app will build the chord or scale of your choosing from the listed buttons. Chord Solver currently has over 20,000 installs and has a 4.5+ rating on the app store.
