Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCart Sync keeps customer carts intact when shoppers switch between devices. When a logged-in customer adds items on mobile and later opens the store on desktop, their cart is restored automatically. No configuration required. The app runs in the background after a one-time activation in the theme editor. Items are validated against current stock before restoration, so customers always see accurate cart contents.
Smart Carts helps boost conversion rates by allowing you to interact with your customers’ carts live. Add urgency by reserving items for customers for a limited time, remind them with automated cart emails, and add items directly to their cart. Track everything with detailed analytics. Improve your customer experience with real-time cart updates, cross-device syncing, and fully customizable email reminders.
