BPM：速度计数器和节拍器。

As someone else mentioned, turning on only the haptics still makes a loud noise. The only way to make it work silently is to actually silence the watch volume, which is obviously silly. For me, when I set it to “vibrate” only, it does nothing. When I set it to “haptic pulse” only, it does pulse but it also beeps! And when I set it to “Audible tick” only, it ticks (nothing wrong there). If you set it to “audible tick” and “haptic pulse” together, it ticks AND beeps! It could be a great simple app but that stuff needs to be ironed out.

There are not many options. I could not make it have half notes, sixteenth notes, triplets, etc. It was not very convenient.

Sometimes it works in the background, sometimes not. Sometimes it keeps steady time, sometimes not. I paid for the version with haptic feedback, and it won’t do the haptic pulse without the tone, even though there’s a setting that suggests it should. Find a better metronome app. This one is a dud.
