I'm a geezer - I use the cell phone AS LITTLE AS POSSIBLE! I'd much rather gaze at tortoise photos on a 27" iMac instead of a little phone screen. I'd rather type on a regular keyboard instead of a little phone screen. And the sound from videos is infinitely better on a nice set of computer speakers than the little bitty things they put in cell phones. So in a nut shell, I won't miss the app because I never knew it existed, and even if I had known, I never would have used it. These young folks and their addiction to the cell phone continues to mystify me...of course, I still dearly miss chrome bumpers on cars.
Thank you for calling me young, but I am 55. Not all of us can afford the luxury of a 27” iMac.
