Pitched Tuner has built in tunings for many common instruments including banjo, bass 4, 5 and 6 string, cello, double bass, guitar including 7 string, ukulele, viola and violin.
This tuning app also works as a pitch pipe and can sound a reference note to tune your instrument by ear (which is always a good skill to practice), or use as a target note when you are re-stringing your guitar/violin/etc.
Hands free tuning means you can tune all of your strings without ever having to touch the screen - you don't want to have to reach for your ukulele tuner in between tuning each string, and now you don't have to.
The instrument tuner shows you the target notes for the instrument and tuning that you have selected - this is particularly useful for stringed instruments.
Pitched Tuner and Pitch Pipe has been designed by musicians to help you quickly and easily tune your instrument using the microphone on your device.
