The caveats

Shopify Theme Detector. Built for merchants copying a competitor's store, not for app vendors. It answers what one store runs, not which stores run an app. Some of its links are affiliate links, including a Shopify sign-up banner, which it says keeps the site free. The dataset figures are its own, and the monthly app spend is an estimate.

WeLookup. Small and new, version 1.0.0 at time of checking. Like every detector, it only sees apps with a storefront presence.
