It is an app that can Vibe & blink LED smartphones without touching.
How to use it is up to you to make and use the subject or among friends, and lover, the notification to get out of a boring long talk.
I began to detect a button "Start" sensing. When I touch the shed ear during a call, hey presto! !
Flashing LED notification for a few seconds and the vibration is performed. LED will flash only during sleep.
Since we are running in the background even if you exit the app, please exit detected "button detection end".
