Head to head
Standard
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartOrbit keeps customer carts in sync across devices and sessions. When customers log in, their guest cart is automatically merged with their existing saved cart, preventing lost items and improving continuity. The app updates cart data in real time and ensures a consistent shopping experience without modifying the storefront design or checkout flow.
On long product pages — especially on mobile — shoppers scroll past the Add to Cart button and lose it. Sticky Add-to-Cart pins a compact bar to the top or bottom of the screen the moment the real button scrolls out of view: product image, title, live price and a one-tap buy button. Tapping it triggers your theme's own product form, so the selected variant, quantity and cart drawer keep working.
