What BOSS Tuner App is
BOSS Tuner App uses a mobile device’s microphone to tune guitars, basses, and other instruments, and to check pitch while singing. Its hands-free chromatic tuner shows a 21-segment meter, note information, and visual tuning indicators. Users can also play reference pitches to tune by ear. The app allows changes to a TU-3/TU-3W-style skin and background color, and includes a newsfeed about BOSS products. On Android, the Google Play listing says horizontal orientation enlarges the meter; it gives a tuning range from A#0 (29.14 Hz) to G8 (6,271.93 Hz) and accuracy of +/- 1 cent. The maker lists iPhone, iPad, and iPod touch compatibility, and the app is available on Android and iOS. Its privacy policy says microphone information is used only to display pitch, is not recorded or sent outside the device, and is not used to collect personally identifiable information. Denying microphone access prevents pitch detection and display. The app is free.
