This BPM counter is exactly what I was looking for. All it does is open, lets you tap out the pulse of what you were listening to, and it calculates the average BPM for however, long you tap.
This means that, if you only tap for four beats or eight beats (1-2 bars), and you tap like a human, it’s likely you will get a slightly inaccurate BPM reading. But if you tap for five or six or seven measures (20-28 beats), you will get almost exactly the BPM of the song you are listening to. I found that to be the sweet spot.
I don’t mind the ads at all because they are out of the way. But I appreciate how basic, functional and not fussy this app is. I hope the developers make money off it.
