Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCustomers add to cart on one device, then buy on another. Ecto saves and syncs each logged-in customer's cart across all their devices, mobile or desktop, so a persistent cart stays ready for 90 days. This cross-device cart sync cuts abandoned carts and drives automatic cart recovery, with no pop-ups, no restore button and no setup. Track cart history and cart insights to spot buying intent.
CartSync Pro automatically saves and restores customer carts across all devices. When a logged-in shopper adds items on their phone and later visits on desktop, their cart is waiting. The app tracks every cart change in real time and syncs instantly using customer metafields. No customer action needed - it works silently in the background.
