which food delivery app do you use?

Why do you want to know, Kseniya? Are you planning to use one? It is a bit rude just to demand that people "please write the name and why you choose this, tell me the pros and cons)" with no explanation. This is a chat site, for you to chat.

Or are you doing research for an article comparing which app is most popular with older shoppers? If so, I think you have to go through Gransnet HQ and pay £30 to put it in Media research requests/

Strange post with no intro, just a direction
Maybe a little more info why are you interested ?

I have home deliveries but I don’t use any Apps.
