I don't think you can call delivery apps a business. I'd say something like "Delivery apps are increasing in Korea".
Say "When a customer orders food by app/on an app ..."
I'd say "Ordering by phone is unnecessary."

The third sentence is unnecessarily wordy, given that you've already mentioned the restaurant and the driver. Try "When the food is ready, the driver picks it up and delivers it to the customer."

When you start a sentence with "And" that way I always wonder what came before.

Perhaps:

Delivery apps are increasing in use in Korea.

If I put the background sentence before it, I'm afraid you would double answer it, as it is already in another thread.

OK.
