I need a complete mobile property app centered on the needs of home buyers. The heart of the build is three features: searchable property listings, a built-in mortgage calculator, and an in-app appointment scheduler that lets users book viewings instantly. Property listings should feel effortless to browse—photos, price, key details, and map location all in one place, with filters for budget, location, and property type. The mortgage calculator has to update payments in real time as a buyer tweaks interest rate, term, or down-payment figures. Finally, the appointment tool should pull available time slots from an agent’s calendar, confirm the booking, then push a reminder to the user. A clean, modern UI is essential, and I’m open to the framework you’re most comfortable with—native Swift/Kotlin, Flutter, React Native, or another solid choice—so long as performance is smooth on both iOS and Android. If a lightweight admin portal or API layer is needed to feed the listings, please include that in your plan. Deliverables • Interactive prototype for quick feedback • Fully functional iOS & Android builds • All source code, clearly commented • Brief technical hand-over and deployment guide If you’ve shipped property or e-commerce apps before, that experience will help you hit the ground running. Let me know which stack you propose, any similar work you can share, and an estimated timeline for the three core features above.
