Keep carts synced across devices for logged-in customers, no more lost carts, no more lost sales.

Casper keeps shopping carts synced for logged-in customers, across all devices. Each cart is saved automatically and stays available for 30 days, even if the customer switches devices. This helps reduce cart abandonment and improve conversion, without popups or manual sync. Once it’s running, you’ll forget it’s there, but your customers will always find their cart, ready to buy.

This app is the perfect solution for our customers who are placing large orders and spending several days building their cart over multiple devices. I had a few questions and Clément was very helpful and responsive in addressing those. Thank you!

So far, not only is this app incredibly helpful, well designed, and easy to use, but support from Clément has been the fastest of any app we've installed to this point.

If your business relies on a persistent cart, this is the app for you.
