Shopify mobile app integration connects an iOS and Android app to the store you already run. The app reads products, collections, prices and availability through Shopify's Storefront API, signs customers in through the Customer Account API and hands the cart to Shopify's checkout, presented inside the app with Checkout Kit. Orders land in the same admin as every other order, with nothing to reconcile.

It suits brands with loyal repeat buyers who want push notifications, saved preferences, faster reordering or features a mobile site cannot offer. The app does not replace your store or copy its data. Payment, tax, discounts and fraud checks stay with Shopify, which keeps card handling out of the app and means a change made in the admin appears in the app without a release.

03What We Do

Capabilities, End to End

Catalogue and cart mapping

Products, variants, collections, metafields, markets and selling plans are mapped to the app's screens, and the cart is built through the Storefront API with buyer context.

Read and write boundaries

The app reads catalogue data and writes only carts and customer preferences. Stock, prices and orders remain owned by the store and are never edited from a phone.

Customer sign-in

Customers authenticate through Shopify's Customer Account API, so one account serves web and app, and no password is stored or handled by the app itself.

Native checkout handoff

The cart's checkout address opens inside the app through Checkout Kit, with your branding, payment methods and checkout extensions exactly as configured for the web.

Failure handling

Lost connections, an item selling out mid-session and expired carts each have a designed path, with requests retried safely and the customer told plainly what happened.

App and API monitoring

Crash reports, API errors, checkout starts and completions are tracked by app version, so a release that harms conversion is seen and rolled back quickly.

06How It Runs

From Kickoff to Launch

Define the reason

Design and connect

Test real purchases

Release and measure

Define the reason

We agree what the app must do better than the mobile site, which store features it needs, such as subscriptions or markets, and confirm your theme and checkout meet Shopify's requirements.

Design and connect

Screens are designed around your catalogue and connected to a development store. Browsing, search, cart, sign-in and checkout are wired to Shopify before visual polish begins.

Test real purchases

Test orders run through every payment method, discount type and market you use, on real devices, and they include poor connections, interrupted checkouts and returning signed-in customers.

Release and measure

The apps are submitted to both stores, released to a share of customers first and measured against the mobile site on conversion, repeat purchase and stability.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP

Your best customers want more than a mobile site

A share of your buyers return often and would use an app for reordering, early access or loyalty. You want that without running a second shop. The catalogue, prices, payments and orders should stay in the Shopify store you already manage.

Repeat purchase brands

Loyalty and member programmes

Drops and early access

Subscription and refill products

Stores selling across markets

Wholesale ordering on phones

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

Book a call

A sales channel or custom app that grants Storefront API access, customer accounts configured for the Customer Account API and a checkout built on checkout extensibility, which Shopify's Checkout Kit requires. Stores still using older checkout customizations need to migrate first. Some features depend on your plan. We check each requirement against Shopify's current documentation at the start and report any gap before design begins.

Through Shopify. The app builds a cart and opens Shopify's checkout inside a native sheet. Card entry, wallets, tax, discounts and fraud screening all happen in that checkout, exactly as on your website. Card details never pass through code we write. Apple and Google have their own rules for digital goods sold in apps, which we review with you if you sell any.

For many stores it is. Template app builders turn a Shopify catalogue into an app quickly and suit brands that mainly want presence and push notifications. Custom integration is worth its cost when the app needs its own features, such as a loyalty mechanic, a configurator, wholesale ordering or a design those builders cannot produce. We give you an honest comparison before you commit.

Yes. Products, prices, collections, availability and discounts are read from the store when the customer opens a screen, so edits appear without publishing a new app version. Layout content such as a home screen banner can also be driven from store data. Only changes to the app's own features or design require a release through the app stores and their review.

Both use the same Shopify customer account. Sign-in happens through Shopify's hosted flow, which sends a one-time code instead of asking for a password, and the app keeps a renewable token in the device's secure storage. Order history, addresses and saved details are therefore identical in both places, and signing out on a lost phone can be handled from the account.
