Straightforward guitar tuner. Single screen app that starts in auto tune mode. Simply run the app, hit a string and start tuning your guitar. Tune into the orange region for a good results or green for perfection.

This app uses your microphone to detect the string being played and indicate if you should tune up or down.

Pitch pipe function also included.

The standard EADGBE guitar (not implemented for very small screen devices) indicates current note being played or allows fast note selection in manual mode.

Tuning range from 30 Hz (B0) to 4186Hz (C8), so can also be used to tune other stringed instruments.
