We will guide you through the process of building a subscriptions app using the Shopify Subscriptions Reference app as a foundational resource.

The Shopify Subscriptions Reference app is an example of how to build a subscriptions application with [Remix](https://remix.run/). The reference app includes the basic features of the Shopify Subscriptions app and serves as a starting point or example app for building subscription applications.

We developed the Shopify Subscriptions Reference app with the following goals:

- **Build a custom subscriptions solution** that meets your commerce needs.
- **Build faster** using the source code from the Shopify Subscriptions Reference app.
- **The core building blocks you need to build an app** that integrates with Shopify’s ecosystem.

> Note:
> The Shopify Subscriptions Reference app serves as the foundation for the [Shopify Subscription application](https://apps.shopify.com/shopify-subscriptions).

## Uniqueness from Subscription Reference app

If you're developing an app based on our Subscription reference app, your app must be distinctively different. You need to introduce meaningful changes and innovations in the design and functionality of the app. Below are some cues that we look for:

Your codebase must have meaningful differences when contrasted with code from other apps.

* The identity of your app submission should be unique.

* Your app should have a clear target industry or niche.

* Your app should have an inventive user interface and experience that distinguishes it from the reference app.

* Your app should provide a cohesive look and feel across all features and screens (for example, subscription management, analytics dashboards, customer communications, and payment processing).

* Your app should offer unique customization options or functionalities that distinguish it from other apps.
