Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureThe average store runs 6–8 paid apps and loses track of the bill. Watchdog maps your whole app stack in seconds: spot duplicate apps doing the same job, find lower-cost swaps, and see invoice-confirmed spend per app. It even flags apps that bill you but never load on your storefront. Audit your stack, cut what you don't need, and stop overpaying — without guessing what's safe to remove.
CostPilot Pro scans your storefront to identify every app you are running. It detects duplicate apps, flags unused subscriptions, and finds cases where a Shopify-native feature already covers what a paid app does. You see all detected apps and their estimated costs upfront. Unlocking individual savings insights is optional.

How Shoplist compares apps
