Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartSpy shows every cart on your store live: each add to cart, checkout and order as it happens, shopper by shopper. Abandoned carts keep their products, including carts left before checkout, which Shopify's abandoned checkouts never list. A daily email sums up yesterday's carts, checkouts and orders, where they came from and what to fix.
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.
