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.

Nice app, working as expected. Plus, we received quick and helpful support when dealing with a problem specific to used theme (Trade theme). Thanks Clément, nice work

I had an issue and I received a fast and good answer, even a follow-up of the situation till they solve it. Thanks Clement

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.

The app works perfectly for synchronizing your cart on multiple devices. I highly recommend this app for this purpose! Thank you Clément for your outstanding customer support too, much appreciated!

Works really well with our custom theme. The only thing is, cart line item properties don't get carried over across devices
