E-Commerce web developer Mobile App

My Shopify store is up and running, but I now need a polished mobile app that mirrors – and improves on – the online shopping experience. I’m after an app that pulls products, collections, prices and inventory directly from my existing Shopify catalogue, lets customers browse quickly, add items to cart, complete checkout in a few taps and receive push-notification updates on orders and promotions.

I’m open to React Native or Flutter as long as the final builds run smoothly on both iOS and Android and pass the respective store review processes. If you have another framework in mind that can work seamlessly with Shopify’s API, let me know and we’ll discuss pros and cons.

Key deliverables:
• Fully branded iOS and Android apps linked to my Shopify backend
• Secure checkout using the store’s current payment gateways
• Real-time sync for products, inventory and pricing
• Search, filtering and wishlist features
• Order tracking with push notifications
• Clean, maintainable source code plus documentation for future updates

Acceptance criteria:
1. Apps approved and live in the App Store and Google Play.
2. All core Shopify data (products, orders, customer accounts) sync reliably without manual intervention.
3. No critical or high-severity issues in TestFlight/Test-Track reviews; usability scores above 90% in our internal QA.

If you have launched successful Shopify-connected apps before and can share links or demos, I’d love to see them and get started right away.
