Have you ever been in a situation when your phone started to ring at the wrong time, and you could not bring it out of your pocket to turn off the ringer? If you have these situations where you want to quickly mute the ringer, which had just started to make noise then this app is for you.
If your mobile phone is in your pocket, or you can not reach the mute key, and someone just start to call, and you have this app, just quickly knock / tap / flick twice the phone and the sound will be muted. This is ideal if you carry the phone in a tight pocket and you have a problem to pull it out.
This application is only activated when there is an incoming call, then the microphone is turned on (which is why this app need the appropriate permission), and the program start to analyze the sound and try to catch "double tap", when it recognize it , then for the duration of call the ringtone is muted.
The operation of application depends on many factors: the sensitivity of the microphone, ring volume and type, vibrations, enclosure resonance, ambient noise, strength of knock, etc. so it is important to adjust the "sensitivity" value to suit your needs, it must be set individually for the user.
In addition, you can set the "speed of knock" - the time between two subsequent knocks
With the right conditions, you can turn off the sound of phone lying away from you by a double clap.

Warning! Some devices might lock microphone when there is incoming connection, in that case the application won't work.
