I need a straightforward yet polished online-shopping app for my supermarket, available on both iOS and Android. The primary goal is letting customers browse products and place orders from their phones; everything else is secondary to a smooth buying experience. Because I’m not on a tight deadline, you’ll have the freedom to choose the tech stack—native Swift/Kotlin or a cross-platform approach such as Flutter or React Native—so long as the final result feels fast and intuitive. Key deliverables I’d like handed over: • Shopper-facing app for iOS and Android, ready for App Store and Google Play submission • Clean, well-documented source code • Simple admin or API hook that lets me update products, prices, and stock in real time • Integrated checkout with a mainstream payment gateway, order confirmation, and push notifications If you already have experience building grocery or e-commerce apps with features like carts, secure payments, and order tracking, that would be ideal. I’m flexible on milestones and open to your suggestions for design, workflow, and post-launch support—quality and reliability come first.
