PitchSetCalc is a tool for music student and theorists that will help with the analysis of music using Set Theory. This app has a simple interface and works on both iPhone and iPad with iOS 10.0 and up. To enter in a new pitch class set, the user simply touches the pitches on the pitch wheel. As the pitches are entered, the app will calculate normal order, prime form, Forte number, and the interval class vector. The pitch wheel will display the pitches using sharps or flats. When the pitches are entered, each one will sound to give the user an idea of how the pitch class set sounds. There is also a playback function which will play the set as either a scale or simultaneity.
