Persistent Cart ‑ Sync Devices vs Swish (formerly Wishlist King)for Shopify (2026)

Persistent Cart ‑ Sync Devices and Swish (formerly Wishlist King) both aim to improve the customer experience and boost sales, but they achieve this through different strategies. Persistent Cart focuses on recovering abandoned carts due to device switching by seamlessly loading the customer's latest cart upon login, eliminating the need for intrusive email reminders or pop-ups. This appeals to merchants looking for a hands-off solution to capture lost sales from cross-device shoppers. On the other hand, Swish offers a comprehensive wishlist solution, enabling customers to save desired products and receive personalized notifications. It caters to merchants who want to build customer engagement and gather valuable insights into product preferences. While Persistent Cart prioritizes cart recovery and increased AOV by addressing the specific issue of device switching, Swish provides a broader suite of features centered around wishlists, including analytics and integrations with marketing platforms like Klaviyo and Meta. This makes Swish a more feature-rich option for brands wanting to foster long-term customer relationships and personalize their marketing efforts. Both apps share the 'Customer loyalty' category on Shopify, but their core functionalities target different pain points within the customer journey.
