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. Merchants also get a Cart Helper tool to manually manage customer carts for support cases. Simple setup — just enable the app block in your theme editor

• Works with any Shopify theme — one-click setup from the theme editor, no code
