NHS covid app - England

[QueryA]

I live in Scotland where we have the NHS Scotland App, which I installed on my phone 18 months ago and have never thought about or used since.

I'm going on holiday to England at the end of next week and I know that there is a different app, but am curious to know how widely used it is? Should I even bother installing it on my phone before I go. I don't want try and check into our campsite and be asked to scan the app and then have to spend 10 minutes downloading it holding up the queue (my phone is a bit shit, has very little free memory, and inevitably I have crappy signal)

So is it widely used? Will I need it to access restuarants etc?

Most places will ask you to check in using (like restaurants, play areas etc). The camp site may not due to needing to keep their own details for track and trace.

I don't have it and have no problems with restaurants etc, they usually just have a bit of paper where you can leave your details.

Yes it's widely used - every venue and shop where I am has it to check in.

Why don't you just download it? Nothing to lose...

I've never had the app and it has never been an issue. Loads of people who downloaded it then deleted it as it is so badly designed.
