I call the local pizza place a couple times a month. I place the exact same order I always do. They ask for my name and phone number each time, but the whole call still only takes about a minute. Who needs an app.
People who want to check for special deals, or who don't know the menu, or who don't want to tie up phone staff on a busy night, or who will take 20 minutes with a group of people trying to decide what to order, etc.
