Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMost merchants only see cart abandonment after the fact — once a shopper is already gone. CartLens gives you a real-time view of cart activity across your store, showing what shoppers are adding, removing, and leaving behind as it happens. This visibility helps you understand shopper behavior, identify where drop-off occurs, and make informed decisions without waiting for end-of-day reports.
RealtimeStack shows you exactly what's happening in your store the moment it happens. Track every product view, search, cart addition, checkout and abandonment in real time — live data, not yesterday's reports. Explore customer activity in a 3D world view and live tables that update instantly.

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 8, 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.
