Simply Tap to the beat of the music. The Beats Per Minute(BPM) will be displayed. Also shown are the Measures Per Minute (MPM) for 3/4 and 4/4 time.
Ballroom Temp Tap, unlike other tap tempo apps, averages the taps giving a more accurate timing. The more you tap, the more accurate. 5 or 10 taps is usually enough.\n
You can also use the shake function. Check the box marked "Shake for Tempo", then shake the phone to the beat of the music.
