Simple, handy and strong Vibrator (body massager).
App gives you an ability to adjust the speed (intensity) of vibrations with single scroll bar slide action (or button press).
Vibration works even if you turn off the screen or minimize the app. There is option to customize your own pace between extremely strong or soft, keeping silent for your privacy.

App has two modes:
1) Simple Vibrator - 4 strength levels.
2) Pattern Vibrator - 4 special vibration patterns - each of them has unique mix of vibrations based on time, acceleration, slowing down, increasing and decreasing of vibration strength.

Simply place where required and activate it. Pleasure guaranteed!
