I want to build a full-featured cab booking application, bringing the familiar Ola/Uber experience to both iOS and Android users. Core functionality must feel seamless for riders and drivers alike, so real-time GPS tracking, secure in-app payments, and a clear driver rating & review flow are non-negotiable. Essential deliverables • Native (or high-performance cross-platform) rider and driver apps for iOS and Android • Real-time vehicle tracking on live maps • Integrated payment gateway supporting cards, UPI, and wallets • Driver rating & review module visible to both parties • Clean UI/UX in line with current ride-hailing standards • Robust backend with APIs, authentication, and notification handling Nice-to-have I’m still weighing the need for a full web-based admin panel to manage drivers, customers, fares, coupons, and disputes. Feel free to outline what the panel would add, the tech stack you prefer, and any extra time or cost implications. Acceptance criteria • Apps approved in App Store and Google Play (testflight/beta builds along the way) • End-to-end ride lifecycle works: booking → driver acceptance → live route → payment → rating • Latency for live location updates under two seconds in normal network conditions • Payment flow passes sandbox and live gateway certification • Complete source code and deployment documentation delivered If you have prior ride-hailing or logistics app experience, mention the tech choices you’d make (e.g., Kotlin + Swift, Flutter, React Native) and any mapping, routing, or payment libraries you prefer.
