I run a professional painting company and want customers to see, in real time, how different paint colours will look on any wall, façade or ceiling before they commit. I need a mobile app built for both iOS and Android that opens the camera, detects interior and exterior surfaces on-the-fly, and lets users swap colours instantly. Please rely on a real-time camera feed rather than static image uploads; smooth edge detection and minimal lag are essential so the user experience feels natural. Core functions I must have: • Colour palette selection drawn from our branded paint range • A before-and-after comparison toggle • One-tap sharing of the rendered result to social media Once the mobile build is ready, I also want the same visualiser embedded on my WordPress website so web visitors get the identical experience without downloading an app. I’m happy to host any required APIs or model files on my own server if that simplifies deployment. Deliverables I expect: • Fully compiled iOS (App Store-ready) and Android (Play Store-ready) builds • Source code with clear comments • Documentation on how the surface-detection logic works and how to expand the colour library • An embeddable web widget or iframe code that mirrors the app’s functionality Please include in your proposal a brief note on the computer-vision libraries or AR frameworks you intend to use and any similar projects you’ve shipped. I’ll test the app on several interior and exterior locations; acceptance is complete when colour masking holds steady under different lighting and the website integration loads without delay.
