Tune Up helps you tune any instrument. it works by finding the note nearest to what is heard, and then shows how flat or sharp it is using a needle on the screen. Tune Up is a chromatic tuner, which means that you can tune to any note, not just particular ones. This is a great help for getting high notes in tune on wind instruments. If you are using a transposing instrument, you can also select its key, for example a Trumpet, Clarinet, or Saxophone. For guitar, piano, and flute choose the key of C.
