Simple BPM Detector

I used this to tune the pendulum on a traditional weight powered clock. I used the metronome setting and dieled everything for max accuracy. I tested accuracy by having it listen to a few digital metronomes and it was dead on. After setting the pendulum timing on the clock I was able to sych it perfectly with a metronome set to the same timeing the app was reading from the pendulum. All in all I'm satisfied with the accuracy and it works really well for this application.

Works well. I tested it against music I have created in my DAW and it was good, never more than +/- 2bpm out and frequently dead right. The more pronounced the beat, the quicker and more accurately it gets the tempo. However it does struggle with music that does not have a strong bass or kick drum groove. Tapping the mic in time with the music, as someone else suggested, helps in those cases. It occasionally displays a bpm that appears very wrong but multiplying or dividing the displayed tempo by 2 often gives you the real bpm.

Got this to help me categorise my vinyls by BPM and have to say so far so good! Sometimes it struggles to get an accurate reading if the drum kick is not very distinctive and there is lots of hi-hat, so I just mute the music and tap on the mic in time with the beat and get the reading that way. Very impressed with the minimal battery drain also, had it on for about an hour and expected battery to be much lower than it was, so great work!
