See every featureShoppers browse across devices, but Shopify carts don’t follow when they switch devices. Persistent Cart prevents lost sales by automatically syncing logged-in customers’ latest carts across devices in the background. No emails, pop-ups, notifications, opt-ins, or code changes — just seamless cart persistence that reduces abandonment, grows AOV, and helps shoppers keep buying instead of starting over.
Shoppers switch devices frequently, but lost carts disrupt the buying experience. This app ensures every cart stays consistent across devices in real time, so customers pick up exactly where they left off. Real-Time Cart Sync keeps carts updated across all sessions. Additions on mobile are instantly visible on desktop, quantity updates are reflected everywhere, and removed items are synced instantly.
- Moves your customer's carts across devices automatically when they switch
- Installs and sets up with 1-click and instantly works in the background
- Automatically clears cart on logout or privacy (optional)
- Cross-Device Sync: Persists cart data for logged-in users across all devices.
- Real-Time Updates: Syncs cart changes like adds and removals instantly.
- Easy Setup: Theme App Extension-based; no theme code modifications needed.
