Cross-Platform Mobile App for Coffee Shop

@rajat07me

The main challenge here is not just building screens from the Figma file, but making the mobile app feel smooth around the real user actions that matter most for a coffee chain: OTP login, modifier-based ordering, pickup store selection, and reliable payment flow. I’d approach this as a clean cross-platform MVP with the API layer, state handling, and checkout logic planned properly from day one so the reorder and loyalty experience do not become messy later. I’ve worked on app flows where the backend was being developed in parallel, and that usually goes well when the mobile side is structured around Swagger from the start with clear fallback handling for incomplete endpoints. React Native or Flutter both work here, but the better choice depends on whether your team wants faster UI alignment with the Figma reference or easier long-term extension after MVP. To help you move faster, I can also keep the build aligned with your existing API documentation structure so testing is easier on your side. - Do you already have the final Swagger definitions for OTP, menu/modifiers, cart, payments, and order history endpoints? - Should the pickup map show all coffee shop branches from the API, or do you want map search/filter behavior as well? - For LiqPay, are you expecting a hosted payment page flow or full in-app card entry handled through their SDK/API?

Hi, I reviewed the request to build a strict cross-platform mobile app client for a coffee shop chain, using your Figma design and connecting to the existing REST API for the MVP features. I’ll implement phone number OTP registration and authorization, the Home screen with bonus balance, loyalty QR code, and promotional banners, plus the Catalog with product modifiers, Cart & Checkout with map-based store selection and preparation time, and Order History with one-click reorder. I’ll deliver clean React Native or Flutter screens that match the Figma UI, handle JavaScript logic reliably, and integrate Apple Pay / Google Pay and LiqPay payments smoothly. Let’s discuss here now.

Hey there! When the backend is already defined, the mobile app should make the API feel effortless not recreate the complexity behind it. I’d build a focused React Native or Flutter client that maps tightly to your REST and Swagger contracts. I would pay particular attention to the OTP flow, modifier-aware cart, pickup location and preparation time, and payment flow so the experience stays consistent from menu selection through order confirmation. Using your Figma as the reference, I’d build reusable components so loyalty, promotions, and one-click reorder can be extended later. Apple Pay/Google Pay, LiqPay, maps, QR scanning, and proper loading/error states would be handled as native mobile concerns where appropriate. Could you share the current Swagger/OpenAPI specification so I can review the endpoints and give you an accurate fixed estimate?

Hello, Your coffee app needs to make the journey from discovering a drink to selecting a pickup location, choosing preparation time, and paying as quick as ordering at the counter. I’ve worked with React Native, Flutter, REST APIs, OTP authentication, loyalty features, maps, mobile payments, and e-commerce-style ordering flows, so I can focus the mobile client around a fast and simple ordering experience. I’ll build the cross-platform app around phone OTP login, bonus balance, loyalty QR, promotional banners, menu categories, customizable products, cart, and checkout. Customers can select a nearby coffee shop through the map, choose preparation timing, pay through Apple Pay/Google Pay or LiqPay card payments, and quickly reorder from their previous purchases. Since your team is already developing the REST API with Swagger documentation, I’ll integrate the mobile application directly against the provided endpoints and keep the implementation aligned with the existing backend contracts. If you share the Swagger documentation and Figma screens, I can map the mobile screens to the API workflows and identify any integration points before development. Regards, Nikita Gupta

@Srashtasoft

Hi there, I have read your project requirements, and you need a cross-platform coffee shop mobile app built in React Native or Flutter, consuming your team’s REST APIs and Swagger documentation. The MVP includes OTP authentication, loyalty/QR features, catalog with modifiers, pickup-location selection, scheduled preparation, LiqPay/card payments, Apple Pay/Google Pay, promotions, and one-click reordering. We can focus entirely on the mobile client, integrate cleanly with your API layer, follow the provided Figma design, and ensure the app is production-ready for both iOS and Android. A few questions: ============= Will the REST API and Swagger documentation be fully available before mobile development starts? Is the LiqPay integration already exposed through your backend APIs, or should the mobile app handle any payment SDK components? Should the loyalty QR code be generated by the app or provided by the backend? Do you already have Apple Developer and Google Play accounts ready for testing and deployment? Best Regards, Srashtasoft Team

@zainalitariq245

Hi, I understand the main challenge is keeping the ordering flow fast while handling OTP authentication, product modifiers, pickup selection and payments consistently across iOS and Android. The second key point is integrating your REST API cleanly so the mobile app stays maintainable as the backend evolves. I’d use Flutter for the MVP, with a structured API layer matching your Swagger documentation. I’ll implement the Figma design closely, including loyalty balance, QR code, banners, catalog, modifiers, cart, map based pickup, preparation time, LiqPay, Apple Pay and Google Pay, plus order history and one click reorder. I’ve built cross platform ecommerce and ordering apps with payment, API and location integrations. Since your backend is already underway, I can focus entirely on delivering a stable, polished mobile client. Business Idea a future loyalty layer could add personalized offers, purchase based rewards and targeted promotions to increase repeat visits across the coffee chain. Is the Swagger API already finalized, or should the app be developed against the current version with flexibility for upcoming endpoints?? Let’s turn your project into measurable results.

Your payment flow will fail certification if you don't handle Apple Pay's merchant validation and LiqPay's 3DS authentication correctly — these aren't simple SDK drops. The QR code scanner also needs camera permissions handled differently on iOS vs Android, which breaks most first-time implementations. Quick questions - what's your expected daily order volume so I can recommend the right state management architecture? And does your backend support webhooks for payment confirmations or are you polling? Here is the architectural approach: - REACT NATIVE: Build using Expo for faster iteration, integrate react-native-maps for shop selection, and implement react-native-vision-camera for QR scanning with proper iOS/Android permission flows. - PAYMENT INTEGRATION: Connect Apple Pay via Stripe or native PassKit, handle LiqPay's redirect flow with deep linking, and build a fallback UI for failed transactions that retries without losing cart state. - REST API CONSUMPTION: Structure API calls with Axios interceptors for token refresh, implement optimistic UI updates for cart changes, and cache menu data locally to reduce backend load. I've built 4 food delivery apps that processed 200K+ monthly orders without crashes. Let's schedule a 20-minute call to walk through your API docs and confirm the integration points before kickoff.
