Standard Guitar Tuner

Standard Guitar Tuner is an easy to use guitar tuner. Just start the app, put it close to your guitar and play a string - you will get the idea in no-time.
This tuner uses the internal microphone to analyze the string you're playing on you guitar. It features advanced signal processing algorithms to allow for fast response and precise tuning.
The intuitive interface tells you if the string is too tight or too loose. A tuned string (+/- 2 cents) is indicated in green and a semi-tuned string (+/- 5 cents) is indicated in yellow.
It can tune your guitar in several custom tunings and it allows you to adjust the reference frequency of A4 to get in tune with an orchestra.
