Question

What mobile apps does GR Trading build?

Answer: GR Trading builds customer shopping apps, staff apps, operations apps, delivery workflows, inventory tools, approval apps, and mobile experiences connected to Shopify, a custom backend, or third-party APIs.

Question

Should a merchant choose a full mobile app or convert a Shopify site into an app?

Answer: Choose a full mobile app when you need custom screens, device features, app-store presence, offline behavior, or complex authenticated workflows. Choose a lighter Shopify-to-app approach when the main needs are home-screen access, push notifications, and app-like browsing.

What we build.

Cross-platform apps with React Native or Flutter, one codebase for iOS and Android.

Native iOS or Android builds when a feature needs it.

Shopping apps connected to Shopify via the Storefront API, or to a custom backend.

Staff or operations apps: field service, inventory, delivery, or approvals.

Push notifications for orders, delivery status, and promotions.

Payment gateway, authentication, and third-party API integration.

Full app, or turn your Shopify store into an app?

If your storefront mainly needs a home-screen icon, push notifications, and an app-like browsing experience, our lighter-weight convert-your-website-into-an-app option under Shopify may fit better and cost less. This page is for a dedicated mobile app: custom screens, device features, and app-store presence.
