I run a brick-and-mortar grocery store and now want to offer customers a full mobile shopping experience on both iOS and Android. The core of the app is simple: shoppers browse our catalogue, add products to a cart, pay, then track the order until it’s ready for pickup or delivery. Key scope • Native or cross-platform build that reaches iOS and Android from the same codebase. • Smooth online ordering flow including product search, cart, promo codes, and a secure checkout. • Payment integration (credit/debit cards and Apple/Google Pay are acceptable). • Real-time order status updates so customers know when their groceries are packed and on the way or ready in-store. • Lightweight store-side console (mobile or web) where staff can see incoming orders and update status. Deliverables 1. Source code repository with clear README. 2. Test-flight/Play-Store ready builds and release builds (IPA + APK/AAB). 3. Payment gateway keys and callbacks configured in staging and production. 4. Brief admin guide so staff can process and track orders. Acceptance criteria • Apple App Store and Google Play Store submission passes review. • Payment completes a ₹1 test order end-to-end without manual intervention. • Order status changes propagate to the customer app within 5 seconds. If you already work with Flutter, React Native, or Kotlin/Swift plus a solid backend stack (Firebase, Node, or similar) that fits this scope, you’ll move quickly here. I can provide product images, SKUs, and necessary API keys as soon as development starts.
