During rehearsals of several dozen pieces, conductors need to verify tempo quickly. However, setting the tempo by tapping or turning a dial takes time, and tapping the next section's BPM while conducting requires advanced skills. That's why an app was developed to allow conductors to quickly enter the desired BPM using a 10-key keypad. The app employs a click sound similar to the UREI Click used as a standard in recording studios worldwide. The app also features a layout where two points alternate blinking in synchronization with the click, making it possible to recognize the tempo even with the metronome sound muted if the app is in view.
