What kind of info are you looking for? CheckoutSmart run the ClickSnap offers for Quidco as well as their own app and website (please be aware that you can't submit the same receipt to both; even for different items).
They have more offers and more retailers on their own app and website. It's possible to use CheckoutSmart entirely via the website however there are some offers that can be only be accessed using the app (offers that require barcodes to be scanned don't appear on the website). They might still do introductory offers for new customers; also some customers can have more or less offers than others.
