[APP] Ringtone Vibrator 1.1 - vibrate your ringtone according to the rhythm

Hey,
I developed a new app today and would like to share with you guys.
it uses the same libs as the Subwoofer Vibrator, but now only on ringtones.
this makes the phone bounce according to the ringtone and not just monotonously.

of course its for free,
you can download from google play by searching for "Ringtone Vibrator"
or directly from google play:
play . google . com/store/apps/details?id=com.ValkA.vibetone

here's a video of how it works:

I'll be happy to hear any comments
