Types of Shopify App:

Shopify apps utilize Shopify REST APIs to communicate with online stores, but they differ in how they reach customers. There are four categories of Shopify apps, each with distinct characteristics. Here's an overview of these app types.

Custom Apps:

Custom apps, designed exclusively for a specific merchant, cannot be listed in the Shopify App Store. They serve the purpose of extending e-commerce to additional channels or enhancing features in the Shopify admin. External app developers can create these customized applications without needing admin access to Shopify or API access to the store.

Public Apps:

Apps for various merchants can be listed in the Shopify App Store. They come in two types: listed and unlisted. The Shopify App Store displays listed apps for retailers to download, but unlisted apps don't appear in search results. Instead, you can find them on the app store or the developer's website.

Draft Apps:

Shopify Partners use these apps for testing during development. They can be installed on development stores that permanently disable store transfer.

Private Apps:

Developers create these apps for merchants with unique needs not addressed by custom apps. Unlike the other two types, users generate private apps in the merchant admin. Private apps are not listed in the Shopify app store and are exclusively accessible for your store. An external app developer will need API access and Shopify admin access to develop these private apps.
