On all cell phones there have been two sensory modes of letting the owner that an incoming call is coming in: auditory (rings & the like) and tactile (vibrate mode). For me, however, because I have a hobby where I am using loud machines that buzz, I often miss call his way. I'm not interested in going through the noise cancelling Bluetooth headsets because the good ones seem to be way expensive. Instead, I'd like to be able to be indicated that an incoming call is coming in through visual means (a flashing light of some sort). Anyone know of any such app out there that does this?
