Our Verdict
If you need to collect specific customer information beyond the standard fields, and prioritize owning your data directly within Shopify's metafields, Amplius Customer Fields is a strong choice.

The ability to uninstall the app and retain the data is a significant advantage.
However, if your primary goal is to boost sales and customer engagement through a wishlist functionality, Swish (formerly Wishlist King) is the better option. Its high rating, large number of reviews, and integration capabilities make it a more robust and widely trusted solution for managing customer wishlists. The free setup and customization service further adds value, ensuring seamless integration with your store's aesthetic and functionality.
