ChromaTuner is a chromatic tuner that provides the most accurate yet simple tool available for its single specific task: tuning musical instruments.
It turns out that hosting a highly-accurate chromatic tuner on the iPhone is a hard problem due to the compression and proximity characteristics of the device’s built-in mic. As a result, other tuners tend to report inaccurate pitches especially at high and low frequencies and when analyzing chords, and their recording sensitivity is often poor. ChromaTuner addresses these problems by employing the venerable C/C++ audio engine FMOD, used in countless high-end video game scores, within an algorithm developed specifically for the iPhone’s built-in mic.
It provides three modes: Chromatic/Auto mode, Manual/Note mode, and Guitar mode; it also includes a tuning fork feature which plays audio tones for all pitches, and the ability calibrate A4 from 430hz to 450hz (with 440hz being the standard). It will remember these settings between uses.
And it does this behind a simple single-screen interface that doesn’t confuse usage with tertiary features. Finally, it’s only 99 cents: a fraction of the cost of a physical hardware tuner.
