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 your guitar. It features a machine-learning pitch engine that runs entirely on your device, allowing for fast response and precise tuning - your audio never leaves your phone. 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 (432-448 Hz) to get in tune with an orchestra. It now also has early support for 7-string guitars.
