Not accurate
Had to download this app since Live BPM mysteriously disappeared from the AppStore. Thought it would be great initially but the read is off. Compared it to my Live BPM app on my phone and the BPM is off by almost an entire BPM. Live BPM read a song at 115.4 that this app says was 116.2. Too far of a discrepancy for me. Also turn off Shazam so it loads the BPM faster. Will keep looking for a better app
