[Request] App that turns on vibration when the phone is inside your pocket
 

The title is pretty much self explanatory. I just want an app for the sensor that activates vibration mode with tone whenever my phone is inside my pocket. Then deactivates vibration when I take my phone out from my pocket. Sometimes I do not hear the message tone when my phone is inside my pocket. I do not want to turn on vibration all the time so as to save battery time. Is this possible?

Another request is to make the phone vibrate when i clck on the status-menu. Just a very very small vibration. Sometimes it does not recognize when i click on the status-menu. So a vibrate when I click the status-menu would be helpful atleast I know the click was recognized

Thanks!
