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.

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!
Thanks so much for the amazing feedback! Really glad Casper has been useful! And it’s been a pleasure collaborating on those improvements. Clément

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.
Thanks so much for the kind words! Really happy Casper is making things smooth for you 🙂 Clément

A simple yet effective app for a very much needed feature that Shopify lacks, and keeps belittling as of today. Clément offered outstanding support and event took our feedback to improve the app, something bigger App developers usually don't do. A must have for any store in my opinion, from small to Plus ones.

Very easy to install and use. Of all the apps that claim to do this function, we found Casper to be the best. Easy to contact the developer directly with questions.

Such a simple solution to such a silly Shopify limitation. Incredibly easy to install and get going. Carts are now syncing across multiple devices, including items with line item properties.
