Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSell the same item as several variants? Different colourway names, a single and a 3-pack, or one product listed twice? OneCount groups them into a pool with one shared stock count. When any of them sells, is refunded, or is edited, every other variant updates within seconds. Set how many units each variant uses, so a 3-pack sale takes 3 from the pool.
Twinstock keeps the stock of your Shopify stores in step, matched by SKU. Install it in each store and link them with a code. Before anything changes, it shows every shared SKU's figures in each store and what differs, and you pick the store to start from. From then on a sale, refund, restock or edit in one store is passed on to the others as the same change, so orders in two stores at once both come off.

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 Nov 3, 2026 for OneCount, Oct 14, 2026 for Twinstock. 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.
