What is FretTune — Precision Instrument Tuner and who is it for?
FretTune is a chromatic tuner for guitar, bass, and ukulele. It offers two ways to read pitch: a needle display and a strobe display, so players can choose the view that suits them. The app runs as a standalone window once installed. It is aimed at string players who want a straightforward tuning tool for these instruments. The tuner works offline, so it can be used without a connection, such as during practice or at a gig.
