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.

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.

1/5No search returns at all
Am a subscriber. Received an email from Which advising Christmas Best Buy’s. Search on Which had no results. In fact, the search function across the board returns “no results” whatever the query. Absolutely useless.

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
