Just to add more comments to this: 0. You can set up favorite orders, and get all the nutrition info you care to. And make fiddly custom orders without worrying someone will screw up typing it in. 1. They don't have to pay a cashier to type in your order if you do it for them. And it's more likely to be correct, and more likely to make upsells (would you like to add a drink to your order?). More cynically, you can't complain that their cashier doesn't understand English since you are now the cashier. 2. Price discrimination. Fast food is an unusual mix of fast and cheap, and not everyone values those two equally. Cheap customers can spend time clipping coupons and browsing app deals while fast customers can make their order via drive through without having to futz around while driving. The app replaces newspaper circulars and mailers, esp now that nobody subscribes to local news anymore. 3. You can order ahead, increasing table turn time, spending less time at their limited seating and limited parking. And you spend less time waiting in line to order, waiting for your order to be prepared. 4. It functions as a loyalty program, buy 10 get one free style (but a bit more complicated). 5. Less fighting over coupons at the counter for the franchisees that don't want to accept them - the app just refuses them. And frankly, some of the penny pincher franchisees may not be savvy enough to set up refusals. 6. If a location runs out of something they can flag it and you won't show up disappointed they can't fill your order. Or they can advertise a per-store menu.
