I saw a fridge that had an app so you could control it from anywhere.
My requirements for a fridge are remarkably simple, to the point the only practical use I could think of an app was alarm that I'd left the door open or something.
(If this particular app did have a door-open alarm, it wasn't on the list of features. It did say you could adjust the temperature from your office. A location I'm often worrying about the fridge.)
Our fridge is most of the time fairly full so I have a hard time imagining where would I put a camera to get a good overview of its contents. It seems that the best place is about half a meter outside. Even a fisheye would not be able to cover both door and the rest of it.
