That ‘undesirable and useless click sound’ is what allows it to sync other instruments to the iPhone. What a dummy! You use this app in tandem with other music apps on your iPhone/iPad and the music goes out mono on one channel, and the click is a “clock sync” square wave on the other channel, which (in some cases must be split using TRS stereo —> dual TS mono cables, and the clock channel) goes into the sync port of your Korg Volca, Monotribe, etc., as well as, the TE Pocket Operators and the OP-1 synth, and nearly any modular synth on the planet that responds to 0.5 VDC <= sync_signal <= 5.5 VDC control voltage signals. The click tells the sequencer when to start and stop and (usually) keeps the tempo in time and can sometimes be divided or multiplied upon by more advanced synths while being sped up or slowed down, keeping the synth in sync with the master clock device (in this case, your iPhone, with the ‘dumb, useless clicking sound’ that it makes 🤣). This app works just as intended, and it is great! Big ups to the developer for creating this utility for my iOS devices!
