I need a clean, intuitive maid-service application that launches simultaneously on iOS and Android. Core flow is straightforward: a customer opens the app, checks real-time availability, books a time slot, pays securely in-app and—once service is complete—leaves a rating and written review. Key modules I must see working end-to-end: • Booking & scheduling with calendar integration and push reminders • Card and wallet payment processing, including automated receipts • Review & rating system tied to each completed job and service provider profile I’m still weighing the value of live, map-based tracking for cleaners; please architect the code so this can be added with minimal refactor if we decide to enable it. You’re free to choose a modern cross-platform stack such as Flutter or React Native, as long as the final builds pass App Store and Google Play submission checks. A simple, well-documented REST or GraphQL backend is expected so the mobile front ends remain lightweight. Acceptance criteria will be a pair of store-ready binaries, companion source code with clear README, and a short Loom walkthrough that demonstrates the full booking-to-review journey on each platform.
