The app says to put in a postal code? Gives no prior warning of what is loaded into it and just gives zero results if you arent in a spot that its meant to serve. I say this as I look directly at a store front with an "order on Just Eat" sign that references this app.
In Canada (Im in Toronto) it does work if you use the website (justeat.ca), which had a very workable mobile version that looks just like the app. Probably less customizable with the repeat orders and such, however.
At least please be upfront or put an alert with the regions that the app covers so people dont have to go about this the hard way. Some other reviews on here I see now say it works in the UK, I guess.
