BOSS Tuner App
What BOSS Tuner App is
BOSS Tuner App uses a mobile device microphone to tune guitars, basses, and other instruments, and to check pitch accuracy while singing. Its hands-free chromatic tuner shows a 21-segment meter, note display, and visual tuning indicators. The app can sound reference pitches for tuning by ear. Users can customize a TU-3/TU-3W-style skin and the background color, and the app includes a newsfeed about BOSS products. The Google Play listing says horizontal orientation enlarges the meter; it lists a range from A#0 (29.14 Hz) to G8 (6,271.93 Hz) and accuracy of +/- 1 cent. The maker lists compatibility with iPhone, iPad, and iPod touch, and the app is also listed for Android. 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 the app from detecting and displaying pitch. The app is free and requires a device microphone.
