McDonald's

At it's best, the app barely works. There is always a quirk or a little bug or just terrible design but you can at least order or redeem a voucher. But from time to time (pretty regularly) there is a fatal flaw or critical bug where the app doesn't open, shuts down immediately after opening, only shows a "no connection" screen, only shows a white screen, etc, etc. I know it's complex to have an app that works in a franchise model but damn, you can't give it more than two stars.

Very poorly designed and executed. The user is near constantly bombarded about accepting or rejecting cookies. The app should remember the user's selection - that's the point of cookies. Navigating back to the menu after viewing an item is a real pain. The app lets you order "McDelivery" but does not let you order for pickup. The user should be able to place an order for pickup at the restaurant of their choice, specify whether they want to pick up at the counter or the drive-thru, and pay.

Extremely slow and unintuitive. Old app wasn't broken. Why the need to change it? Oh because you have some arbitrary KPIs to fulfill? Takes like an hour, to load the deliveries. Might I add the delivery portion is coded so bad, it doesn't even tell you how much a different drink or an add-on will cost you, whereas if you choose order for dine in, it'll show the prices for each add-ons.
