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 a game-changer - well-priced, incredibly effective, and solves a major shortcoming in Shopify’s native functionality. Since implementing it, we've seen a significant boost in customer satisfaction. Clément is highly responsive and has even implemented new features based on our feedback. Couldn't recommend it more - truly a 10/10 experience!

App is working well - I had a little hiccup but I reached out to customer service and they replied in under a day, and were able to help out. Very friendly service- Definitely recommend.

Pooff just like that, carts were disappearing. Can you imagine Shopify tokenizes carts and doesn’t sync them across accounts? I know it’s hard to believe. In comes Casper, and without any issues, it just works. Carts are now synced effortlessly between devices for our logged in users. Definitely recommend.
