Addresyo Lock vs Swish (formerly Wishlist King)for Shopify (2026)
Addresyo Lock and Swish (formerly Wishlist King) are both Shopify apps with perfect 5/5 ratings, but they cater to vastly different needs and target different types of Shopify merchants. Addresyo Lock is a highly niche app focused on ensuring billing addresses remain the default, addressing a specific concern about address synchronization issues during checkout. Its primary strength lies in its simplicity and focus, aiming to resolve a single problem efficiently. Swish, on the other hand, is a comprehensive wishlist solution designed to enhance customer engagement, drive sales, and improve customer satisfaction through personalized notifications and advanced analytics. Formerly Wishlist King, Swish's rebranding reflects its broader ambition and expanded feature set. While both apps are listed under 'Customer Loyalty', their approaches to achieving this goal are fundamentally different.

Our Verdict
For merchants specifically struggling with inaccurate default addresses after checkout, Addresyo Lock offers a straightforward and effective solution. Its value is in resolving a very particular pain point. However, given the minimal number of reviews, merchants may want to consider the risk associated with a relatively untested app. Swish (formerly Wishlist King) is the better choice for the vast majority of Shopify merchants seeking to improve customer engagement, drive sales, and gather valuable customer insights through a feature-rich wishlist solution. The significantly higher number of reviews suggests a more mature and widely adopted product, despite both holding perfect ratings.
Common Questions
Which app is easier to set up?
Addresyo Lock is described as easy to use because it integrates as part of Shopify Flow, suggesting a simple setup if the merchant is already familiar with Flow. Swish offers free setup and customisation service, implying a potentially more complex initial setup that is handled by the Swish team.
Which app offers better analytics?
Swish provides advanced analytics and wishlist curation features, offering insights into customer behaviour and product preferences. Addresyo Lock does not offer any analytics, as its function is purely operational.
Which app is more likely to directly increase sales?
Swish is designed to directly increase sales by enabling customers to save desired products and receive personalized notifications. Addresyo Lock indirectly contributes to a smoother checkout experience, but it doesn't directly drive sales.
Which app is more privacy-conscious?
Addresyo Lock explicitly states that it does not store customer information, suggesting a higher level of privacy. Swish, by its nature, collects customer wishlist data and purchase behaviour to personalize recommendations, requiring robust data security measures (which are presumably in place, but not explicitly stated).
Are both apps suitable for all Shopify themes?
Swish explicitly states that it integrates with all themes. Addresyo Lock does not make this claim, although its Flow integration suggests compatibility with most modern themes that support Flow.
