Horrible! Dont bother with the coffee loyalty part.
If the point of this app was to show that McDonalds has no idea how to employ an app for loyalty and marketing. Id give zero stars if possible.
I use numerous apps for discounts at restaurants, among them Starbucks, Panera, and Dunkin Donuts. All of these show up the McDonalds app. The deals are rarely worth it unless you spending a lot. As for the coffee loyalty portion, no store Ive been to understands how it works. I bought six coffees at seven visits; five coffees should get you a free drink. A few times I never received credit for the coffee drinks, and after finally reaching five, I never received notification of the free drink, and the app erased all of the stamps showing my progress.
McDonalds, Im uninstalling your app until you work out the bugs and educate your stores on how it works.
