Propel Subscriptions App vs Swish (formerly Wishlist King)for Shopify (2026)

Propel Subscriptions App and Swish (formerly Wishlist King) both aim to enhance customer loyalty, but they approach it from entirely different angles. Propel focuses on recurring revenue streams through subscriptions, offering a streamlined subscription management experience with features like automated billing, customer portal, loyalty-based discounts, and customizable notifications. This app targets merchants seeking to establish and optimize subscription-based offerings for their products. Swish, on the other hand, provides a wishlist solution designed to capture customer interest and drive conversion by allowing customers to save desired products and receive personalized notifications. Swish prioritizes customer engagement and conversion optimization through its wishlist functionality, advanced analytics, and integrations with marketing platforms like Klaviyo, GA4, and Meta. Its free setup and customization service also appeals to merchants who want a tailored solution without added complexity. Both apps have strong ratings, but Swish boasts a slightly higher rating and a greater number of reviews, suggesting a broader user base and potentially wider appeal. Choosing between the two depends heavily on whether a merchant's primary goal is to generate recurring revenue through subscriptions or improve customer engagement and conversion rates through wishlists.
