Diagram showing how storefront, buyer identity and checkout can be combined when building a mobile app

## How it works Shopify provides a suite of libraries that enable developers to deliver best-in-class, mobile app commerce experiences for buyers: build custom storefront and product discovery flows, integrate identity with sign-in and account management, and accelerate buyers through a contextual and personalized checkout process. ## Storefront Shopify’s Mobile Buy SDK’s enable you to create and embed custom storefront and product discovery experiences within your mobile app. The SDK’s interface with the [GraphQL Storefront API](/docs/api/storefront) to fetch information about products and collections, and to assemble a personalized buyer cart with contextual buyer information.

Shopify provides support for built-in identity solutions, integrations with third-party identity providers, and cart-driven workflows for optimizing guest and new buyer checkout journeys.

## Checkout Sheet Kit Shopify’s Checkout Sheet Kit enables you to provide the world’s highest converting, customizable, one-page checkout directly within the native app. The experience is a fully-featured checkout that preserves all of the store customizations—e.g. branding settings, UI extensions, Functions, and more.
