Does Zyft work in a retail App?

Zyft is a browser extension so it only works on a web browser, either on mobile or desktop. Zyft, by its nature of being a browser extension, is not able to provide price comparisons while you're searching on a retailer shopping App. If your favourite retailer has an App, you can always search on their website so Zyft can shop with you, so you can compare, shop, and save!
