Mobile Chromatic Instrument Tuner
This application helps you tune your instrument: piano, violin, guitar etc. It uses advanced algorithms to discover the fundamental sound frequency (supported range: 50-1100Hz). The measurement correctness strongly depends on the microphone recording quality. Place your phone as close as possible to the audio source. The application also contains a tone generator which can generate tones from the scale - for best results, use it with headphones. Version 2.0: better tuner and tone generator.
