BU-Chord is not an application that displays all the chord diagrams.
Each chord shows several registered patterns, which are selected as most simple and useful. Please understand that unregistered diagrams cannot be searched.
The app supports left handed.

In this version all chords can be seen without charge. If you remove the ad for a fee, the fingerboard will be displayed even larger.
