In this mode, you can easily feel the beats with flashes of light. Project the flashlight to the wall, then the entire wall can flash the beats. ★ Large and simple button Start or stop the metronome with a big button whenever you want ★ More features • Supports all instruments, such as active piano, guitar, ukulele, mandolin, violin, cello, viola, bass, drum, flute, harmonica, etc. • Supports all kind of transposed instruments, including B-flat clarinet, F horn, E-flat saxophone, D-flat piccolo, and many others. • Scales practice • Precise beats per minute (BPM) control • BPM detector • Practice time tracker • High precision tuner • Visual metronome mode using flash light of the camera • Tuning fork, pitch pipe ★ About permissions Android 6 or above: Access to microphone is for recorder and tuner, and access to storage is for recorder. Below Android 6: Additionally, access to camera is required for flash light metronome, access to phone status is required to stop the metronome when a call is incoming(, which is disastrous when it's not).
