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.
