Judge.me is a great review app. Frontend most review apps look more or less the same. You have some stars, a name and a review. Backend is where Judge.me shines.
Easy to use, easy to customize and EXCELLENT for shops in languages other than English, as you can easily translate everything on one place on the dashboard.
Of course I managed not to find this dashboard (which is PEBCAK because it's as simple as clicking 'settings' in the app), but with excellent assistance from Tony at customer service (shoutout to Adam at Shopify CS too) I was guided to the right place and could easily do everything I needed to make the review section look great.
10/10, would recommend.
