Airbnb-Style Car Rental App

I’m planning to launch a simple, fast, and modern car-sharing application that works on both iOS and Android. Think “Airbnb for cars,” where owners can effortlessly list a vehicle and renters can find, book, and pay in just a few taps.

Core functionality I must see from the first release:
• Car listing with photos, specs, real-time availability, and location-based search
• End-to-end booking flow tied to a secure, in-app payment gateway (card + wallet support)
• Ratings and reviews so owners and renters can build trust quickly

The UI should follow a clean, modern design language—minimal screens, bold typography, intuitive iconography, and snappy transitions that feel native on each platform. Smooth performance is essential; long load times or cluttered layouts won’t work for this project.

I’m open to the stack that best delivers speed and maintainability (Swift/Kotlin or a robust cross-platform option like Flutter or React Native). What matters is that the final build passes App Store and Google Play submission, and the codebase is clear enough for future updates.

Please outline:
• Your proposed tech approach
• Estimated timeline with key milestones (alpha build, beta test, store-ready release)
• Any similar apps you’ve launched that demonstrate these exact features

I’m aiming for a fair, transparent price and a collaborative partnership that gets this app into users’ hands quickly. Let’s discuss how you can make it happen.
