Method and limits

StoreRadar.co checks public Shopify storefronts and counts the app signals it can see. We checked this group on 22 September 2026. Counts can change as stores and their tools change.

A signal is a clue from a public storefront. It is not proof that a store pays for a tool, wants to buy, or has a certain result. The category label is our way to group similar tools.
