Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureRunning a sale usually means editing prices by hand and hoping someone remembers the originals. This app previews every variant change before it is written, stores the exact original values, and restores them when the sale ends or whenever you choose to roll back. Target products, collections, saved searches, or the whole catalog.
ZeroPrice Guard helps you find products with variants priced at $0.00 so they can be reviewed before shoppers see the wrong price. The app adds or removes your managed tag, supports manual syncs, keeps an activity history, and can optionally draft active products when draft protection is enabled.

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
