I’m building a full-service platform that lets travellers book vehicles directly from multiple rental agencies, and I need both a mobile application (for iOS and Android) and a matching website completed within the next month. The experience has to feel modern and sleek from the first tap: clean screens, intuitive flows, bold typography, and a consistent visual language across phone, tablet, and desktop. Users should be able to search nearby cars, filter by class or price, view high-resolution photos, and finalise their reservation with secure in-app / on-site payment. Push notifications and email receipts will confirm each step. For rental agencies, I require a portal to upload cars, set pricing, block out dates, and accept or decline bookings. A lightweight analytics view showing fleet utilisation and revenue would be ideal. All of this should be driven by a single backend API so data stays perfectly in sync between the apps and the website. Key components I expect at hand-over: • Universal UI kit and brand guidelines that reflect the chosen modern aesthetic • iOS and Android builds ready for App Store & Play Store submission • Responsive web front-end published to my hosting provider • Admin / agency dashboards with role-based access • Database schema, API documentation, and test credentials • Source code in a private repository, plus a short hand-off call or video walkthrough Feel free to recommend the tech stack—whether Flutter, React Native, Kotlin/Swift, or a web-first framework—as long as performance is smooth and the design vision stays intact. If you’re confident you can deliver a polished MVP inside four weeks, let’s talk about the roadmap and milestones.
