4/5Frozen, cannot use this app
I downloaded this app as the reviews were good. All was fine until the app tried to log me into my Which? account. A pop-up window came up and completely froze the app. There was no way to close the pop-up and it did not respond to scrolling. I uninstalled the app and then reinstalled it. No joy. Eventually i rebooted the mobile and that fixed the problem. Overall a rather frustrating start but the app works well, once it works.

4/5No sync with their web site
It’s a good app, but if you shortlist something you can’t see that on the web

5/5I wish…
I wish I knew then what I know now from researching everything on Which? from finance to health product and home goods. Excellent consumer advice!

4/5Which?
Convenient reference when on the go, and to remind one of the Which? magazine articles.

2/5Great content, terrible app
The app is horrible to use and constantly freezes. Also it doesn’t remember the saved items as I found my list is suddenly gone.
