Tired of using your fingers for BPM counting? With BPM Shaker you can simply shake your iPhone or iPod touch to the beat and get an instant readout of both average and current BPM values as well as the difference between two consecutive BPM count updates.
For your convenience, a graph gives you visual feedback of the force you apply to the device and the beats it detects from your movement. This gives you the chance of adjusting your movement for perfect beat couting.
An additional feature helps keeping the beat count accurate after you were interrupted or made a mistake. For those who don't like to shake, a Tap mode is also provided.
Have fun and let me know what additional features you could use!
