I need a single mobile application, published for both iOS and Android, that acts as a digital host for more than 30 holiday apartments. When a guest opens the app they should immediately see a personalised welcome letter, the current local weather and everything they might ask me about the unit—door key code, Wi-Fi credentials, distance to the city centre, bus station and beach, house rules, checkout time, you name it. Every apartment has different details, so I want one central admin dashboard where my staff and I can log in, pick an apartment and quickly update text, swap photos or toggle features without touching any code. A templating approach is fine as long as each property can display its own content and styling. Extra guest-service modules are essential: • “Full fridge” grocery pre-order • Rent-a-car enquiry • Transfer / shuttle request Those requests should trigger an email or in-app notification to our team and store the data in the database for later reporting. The app must also push guest registration data directly to Croatia’s eVisitor system via their official API (I can supply the documentation and test credentials). I’m open to React Native, Flutter or another cross-platform stack that lets us maintain a single codebase and still deliver a polished native feel. Once development is complete I expect: • Production-ready iOS and Android builds uploaded to my Apple and Google accounts • A web-based admin dashboard hosted on my VPS (Laravel, Node, Django—your choice, just keep it secure) • Source code in a private Git repository with clear readme • Short hand-over session so my team can create new apartments and update content on their own If this sounds like a challenge you’d enjoy, tell me how you would structure the project and which third-party libraries or services (weather API, push notifications, etc.) you prefer to use.
