Key detection app for mobile devices

Auto-Key Mobile delivers a fast, accurate, and portable way to automatically detect the musical key of any song—all from your mobile device. Simply tap a button, hold the microphone on your phone up to any audio source playing music, and the key will automatically be detected and displayed as both the major and relative minor.
