In Shopify, App Blocks and App Snippets are two different ways to integrate and display app functionalities within your store, but they serve different purposes and work differently.
Here's a quick breakdown of the differences between App Block and App Snippet:
App Blocks are more user-friendly, flexible, and customizable without needing to edit code, making them ideal for modern themes.
NOTE: Kiwi is using sizing injector to move the size chart anywhere you want from your product page. You can learn more about it from this article: How to change where size chart shows on product page using Sizing Injection Selector?
App Snippets are code-based, static, and require manual placement in the theme, which might be better suited for older themes or specific customizations.
NOTE: Please contact our team if your app does not support App block so we can add the snippets to your theme manually.
