Разработчик приложения BPM Tap Calculator: Darren Gates
Compute BPM (Beats Per Minute) for any song. Simply tap at a consistent tempo into the central target, and Tap Calculator will compute the tempo in beats (taps) per minute, also known as BPM. Think of it as a sort of "reverse metronome".
This application is great for music DJs, musicians, dancers, and anyone else who may need to quickly compute the beats per minute of a song simply by listening to it and tapping the tempo.
This app is a single user interface, and is meant as a quick and dirty way to get a BPM estimate with just a few taps of the finger.
