DIFF leads with an offer that is hard to ignore, Buy 1, Get 1 Free, plus a give-back promise ("we've helped over 4.5 MILLION people") and big proof (74.91K reviews sitewide, 1,268 on the Cleo). The homepage has no H1 and is busy with a Yellowstone collab preorder, a store opening and BOGO banners, so the give-back story that sets DIFF apart competes with promotion noise.

DIFF Eyewear: on the pageReviews show on the product page (No rating near the title). We couldn’t name the app from the page code, so it doesn’t count as a gap.
Post-purchase experience
Not spottedOnly 17% of peers run one, so it doesn’t count as a gap.

Not spottedOnly 10% of peers run one, so it doesn’t count as a gap.
Adoption is the share of storefronts where our Oct 9, 2026 scan found at least one app in the lane. Apps that live only in checkout or the back office can hide from a scan, so “not spotted” doesn’t mean missing. App names show what other brands run. They aren’t endorsements. A few links to software partners are referral links, and we may earn a commission if you sign up, at no cost to you. Money never changes a score.
