I want to launch a clean, user-friendly mobile application that lets customers in Saudi Arabia book limousine services directly from their phones. The app’s sole focus, for now, is booking rides. Users should be able to choose between two ride types—single trip or round trip—and confirm each reservation instantly within the app. A seamless, secure payment gateway is essential. Once a rider selects the trip type, the flow should proceed to fare display and in-app payment (credit/debit cards and common local wallets; advise me on the best SDKs). Real-time vehicle tracking, driver choice, and other advanced options can wait for later versions; I first need a rock-solid booking core. Deliverables • iOS and Android builds (store-ready) • Admin or dashboard panel for trip management • Source code with clear documentation • Tested payment integration and sample sandbox credentials • Basic brand-aligned UI/UX screens (logo, color palette provided once we start) Acceptance Criteria A ride can be selected (single or round), priced, paid, and confirmed without crashes or dead ends; I can see the reservation appear instantly in the admin panel. NOTE: App will be revised and modified by adding or deleting some skills throughout while the process until the final version is approved by me without extra charges . If you have prior experience with ride-hailing or travel apps and can suggest the most reliable payment libraries for the Saudi market, I’d love to hear how you would approach the build and timeline.
