Field notes
The described workflow uses a pure sine tone that follows a finger across a logarithmic frequency tape, with a drag across the response chart also available for auditioning frequencies. The page says profiles can be saved or backed up as files and imported on another phone. Its origin section names the upstream project, lists the files ported to Kotlin, and explains the licensing attribution; it also distinguishes the new GraphicEQ export from the ported code.
