Can I earn by shopping on a brand's app, instead of their website?

No—in order to qualify for online earnings from a brand, you must complete your purchase directly on the brand’s website (not their app) after clicking from FlipGive.

If you do not complete a purchase on the brand’s website by the Earn By date (noted next to the shopping trip in Order History > Shop Online > All Shopping Trips), you will need to return to the brand’s detail page on FlipGive, click Shop Now again, then complete your purchase.
