Is there an app that will send a text with a predetermined message when a call is missed without me even knowing I missed a call? For instance if I was running a loud piece of equipment and I do not hear the phone ring or feel it viberate on an incoming call and I make a message that saids (I am on the bull dozer and did not hear the phone. I will call you back.) I have seen a few apps that do something close to this and I have even bought one but they all seem to require you to press the trackball or something before the SMS is sent. Thanks
