The goal is to create a first-person, point-of-view mobile app that lets users explore a typical UK house and interact with key objects. The build needs to run smoothly on both iOS and Android and only requires a basic level of graphical fidelity; simplicity and responsiveness matter more than high-end visuals. Core interactions • Doors: tap to open and close, complete with a modest sound cue. • Lights: toggle on or off, changing the room illumination in real time. • Cupboards / drawers: open and close with a simple animation. • Pop-up tips: context-sensitive text bubbles that appear when the user nears an interactive element, offering short hints or safety advice. Technical expectations • First-person navigation (standard FPS touch controls or joystick). • Lightweight 3D assets or low-poly models to keep the install size small and frame rate high. • A single codebase—Unity, Godot, or another cross-platform framework is fine as long as you deliver both APK and IPA builds plus full source. • Clean, commented code so I can tweak text, swap textures, or add new objects later. Acceptance criteria 1. Every listed object reliably opens, closes, or toggles on both OSs without crashes. 2. Pop-up tips trigger only once per interaction and vanish on user tap. 3. Navigation feels smooth on an average mid-range device (30 fps target). 4. Final delivery includes compiled builds, project files, and a brief README explaining scene hierarchy and how to replace assets. If this scope fits your skill set, let’s get started. I am new to this but already know what I want this app to be, I just need someone on the app building side of things

Hi there, I have read your project requirement — you need a cross-platform first-person 3D mobile app with interactive objects (doors, lights, drawers) and smooth performance on iOS & Android. We will build this using Unity (single codebase) with lightweight assets, smooth FPS controls, and reliable interactions (open/close, toggle, pop-up tips). The app will be optimised for performance (30 FPS on mid-range devices) with clean, well-commented code so you can easily update content later. Quick questions: ============= Do you already have 3D assets or should we create low-poly models? Any reference for movement style (joystick vs tap-to-move)? Should tips be static or configurable from a file/admin? Target devices range (low-end or mid-range focus)? Best Regards, Srashtasoft Team

Hi, I can build your first person interactive UK house app as a lightweight, smooth running mobile experience for both iOS and Android. I have experience working with Unity based mobile apps and interactive 3D environments, and I can translate your concept into a simple, stable, and easy to extend project. I will create a clean first person controller with smooth touch navigation and optimized low poly environment so it runs well on mid range devices at a stable frame rate. All interactions like doors, lights, cupboards, and drawers will be fully functional with simple animations and sound feedback to keep the experience responsive and intuitive. I will also implement context based pop up tips that appear when the user approaches interactive objects, with logic to ensure they trigger only once per interaction and disappear cleanly when tapped. The full project will be built in a single Unity codebase so you receive complete source files along with Android and iOS builds. The final delivery will include organized scene structure, clean commented scripts, and a simple guide so you can easily change text, swap assets, or add new interactive objects later without needing deep technical knowledge. Best, Justin

Hey, this sounds like a fun little project. Do you already have the 3D house and objects, or should I use simple placeholder models first? Roughly how many rooms should the house have? Do you want sound for other things too (like drawers/cupboards), or just doors? Will the tips text be something you provide? we can start with a quick version of the house and interactions and build from there ?

Hi I can build your first-person mobile house exploration app for both iOS and Android with smooth controls, simple 3D visuals, and interactive household objects. The main technical challenge is keeping the app lightweight and responsive while making doors, lights, drawers, cupboards, sound cues, and pop-up tips behave reliably on both platforms. I have experience with Unity, Godot, mobile app development, 3D scene setup, FPS-style touch controls, low-poly assets, interactive object scripting, lighting controls, UI pop-ups, audio triggers, and Android/iOS builds. For this project, I would recommend Unity because it is reliable for cross-platform mobile builds and makes it easy to manage 3D scenes, interactions, and future asset changes. I can create a typical UK house layout with tap-to-open doors, light toggles, simple cupboard/drawer animations, proximity-based hint bubbles, and clean code so you can update text or replace textures later. I can also provide APK/IPA builds, full project source, and a short README explaining the scene hierarchy, scripts, and how to add or swap assets. Thanks, Hercules

Hello, Your app idea is clear and very achievable, and I can help you build a smooth, lightweight first-person UK house experience for both iOS and Android using Unity. I’ll focus on responsive controls, optimized low-poly assets, interactive doors/lights/drawers, and clean pop-up tip systems that feel natural and easy to expand later. You’ll receive: • APK + IPA builds • Full Unity source project with clean commented code • Smooth FPS controls optimized for mid-range devices • Easy-to-edit structure for future updates and new objects A few quick questions before we begin: • Do you already have a floor plan/reference for the UK house layout? • Would you like realistic or slightly stylized visuals? • Should the pop-up tips focus on safety training, education, or general interaction? • Do you already have sound effects/voice assets or should I include them? I can start immediately and keep communication fast throughout development. Best regards, Neelam ZENDXB

Hi, I went through your scope carefully, and the important part here is keeping the app lightweight and responsive rather than overbuilding visuals that hurt performance on mid-range devices. The interaction flow also needs to feel reliable and intuitive on mobile, not clunky like many first-person apps. I can build this with clean structure and scalable logic for doors, lights, drawers, and pop-up triggers while keeping the project easy to expand later. You’ll receive both Android and iOS builds along with organized source files and documentation for future edits. I’ve worked on interactive 3D environments before, so handling FPS controls, optimized assets, and smooth object interaction won’t be an issue. One thing I’d like to ask early: do you already have a preferred house layout/reference in mind, or would you want the environment designed from scratch around the interactions? Best Regards, Muskan
