I need a robust mobile application that talks directly to my Raspberry Pi-based device and guides users through a short diagnostic workflow. The same build must run smoothly on both iOS and Android. . Require to be done quickly. Developer should have proper knowledge of mobile app dev as well as able to link the mobile app with RPI as per standard protocols via wifi/Bt. YOU MUST HAVE ACCESS TO RPI TO CHECK AND TEST. APK LINK [login to view URL] Please note this is a client project hence provide rational quotations. Irrational quotations will be ignored. App flow • Screen 1 – discover, pair and stay connected to the Raspberry Pi. • Screen 2 – present a short questionnaire and store responses locally until upload. • Screen 3 – wait for the device trigger, show the captured image, let users review three separate image sets and confirm each one. • Screen 4 – once the next device trigger arrives, display the sensor values streamed from the Pi in real time. • Screen 5 – collect follow-up diagnosis tags in a second questionnaire. • Screen 6 – push everything from screens 2-5 to an online database, showing progress and success/fail feedback. IN TERMS OF EXISTING APK THE FOLLOWING CHANGES - screen 1 same , 2 we need to create , 3 - update to take muliple images with retake confirmation , 4- update currently part of screen no 3 create a sep screen + optimize , , screen 5 not req as mentioned, screen 6 - from scratch (backend as well). Authentication A simple email-and-password log-in is mandatory before anyone reaches the pairing screen. Backend I need a lightweight RESTful API that the app hits for sign-up / sign-in, image and sensor data uploads, and any future analytics calls. Please design the endpoints, database schema, and secure token flow; the Pi side already sends its data over the local network once a connection is open. Deliverables • Production-ready source code for the mobile app Flutter • API code with clear documentation and environment files for rapid deployment to a cloud host (AWS, GCP, Azure or similar). • Build instructions plus a short video or screenshots proving the full workflow on both an iPhone and an Android device. The key success criteria are reliable device pairing, instant image preview, lossless data upload and a clean, intuitive UI that feels identical on both platforms. If this matches your skill set, let’s get started right away.

Hey, I can take this on and deliver a production-ready Flutter app that pairs with your Raspberry Pi (Wi-Fi and Bluetooth), implements the six-screen diagnostic flow you described (email/password auth → pairing → questionnaire → multi-image capture with retake/confirm → separate real-time sensor screen → final upload UI), and ship a lightweight REST API + DB for sign-in and data/image uploads. I’ll update Screen 3 for multiple images with retake confirmation, split out the sensor view as Screen 4, build Screen 6 and the backend from scratch, and provide clean, commented source code, signed iOS/Android builds, a short demo video showing the whole workflow on both platforms, and deployment notes for the API (AWS/GCP/Azure). I do require access to an RPi you can share (or remote test access) to reproduce pairing and streaming during dev. Depending on access/testing time and any extra edge-case device drivers; I can start as soon as you confirm access details and provide the APK/test Pi endpoint.

Hi there, I can convert your existing APK into a polished cross-platform Flutter app that pairs with the Raspberry Pi (Wi-Fi/BLE), walks users through the diagnostic flow, and uploads results to a secure backend. I’ve built similar Pi ↔ mobile integrations and will deliver a reliable, testable workflow quickly. What I’ll deliver: • Flutter mobile app (iOS + Android) with email/password auth, device discover/pair, local questionnaire storage, multi-image capture + retake confirmations, separate sensor stream screen, and final upload progress/status. • Lightweight REST API (Node.js/Express + PostgreSQL or Firebase) with auth tokens, endpoints for sign-up/sign-in, image & sensor uploads, and simple schema docs. • Robust pairing (BLE & local Wi-Fi modes), retry/queue sync for offline, and secure TLS token flow. • Full source, build scripts, deployment notes, and a demo video showing end-to-end runs on both platforms using your Pi/APK. I’ll need access to the Pi (network) and the APK you shared for compatibility testing — I’ll reproduce and improve the changed screens you listed. Best regards, Shuvadeep.
