This software is a chord reference app for instruments such as guitar, ukulele, mandolin, and bouzouki with various tunings. It features a reverse chord finder and supports both standard and custom tuning.

What sets ChordAid apart is its sophisticated algorithms, which enable it to produce high-quality chord charts. These algorithms allow it to work flawlessly with both standard and custom instrument tunings. The application also provides the option to view more challenging chords, including those with two barres and wide finger stretches.
ChordAid allows users to display, compare, and practice multiple chords simultaneously. Users can either choose chords from a song or different variations of the same chord. The software also provides the option to mark favorite chord shapes and switch to a display mode that only shows these favorites, thus enabling users to create a chord library of their own.
Moreover, the application facilitates the transfer of chord shapes to other software via drag-and-drop. These shapes can be exported as resolution-independent PDFs or bitmaps. ChordAid's versatility extends to its ability to help users identify the possible names of a chord by selecting the frets that have been played on a virtual fretboard.
Overall, ChordAid is a comprehensive software that exceeds expectations with its expansive chord library, advanced chord chart production technology, and numerous customization options. Its capabilities make it a valuable tool for musicians of all levels.
