Pricing moves in SKU and barcode

Weekly rankings of public Shopify apps, each built on one named rule: the apps gaining the most stores, the most-installed, small apps breaking out, apps climbing Shopify’s own category ranks, review surges, big-brand favorites, rookies, Shopify’s featured apps and pricing changes.

A store Shoplist had already crawled without the app that now runs it, or a store coming back to it. A store crawled for the first time, a new detector recognizing an app that was already there, and a store returning after a long gap are labeled and never counted.

Every Monday, from the trailing complete days. Each week is archived with its ranks, so movement arrows, NEW and weeks on chart are real history.

Apps that changed a price, added or removed a plan, or changed their free plan in the 28 days before the week, and kept the change, most-installed first. Unlisted apps and Shopify’s own apps are left out, and the store-movement charts leave out an app while one of its days is held for review.
