I need an end-to-end mobile application that pulls real-time data from a medical-grade watch—heart rate, blood pressure and oxygen saturation—then combines those readings with a tongue photograph (Traditional Chinese Medicine style) and a short in-app questionnaire. Once the data is collected, an AI engine should run symptom analysis, risk assessment and personalised health recommendations. I also want the system to suggest eating-behaviour adjustments and tailored TCM herbal tea options. For reasoning, the back-end may chain or ensemble multiple LLMs (DeepSeek, ChatGPT and Google AI) so the user receives a concise, evidence-based summary rather than conflicting opinions. Key deliverables: • Mobile app (iOS/Android) that pairs with the watch and securely stores heart rate, blood pressure and SpO₂ readings. • Camera workflow that guides the user to capture a clear tongue image. • Dynamic questionnaire builder so I can add or modify health questions without a new release. • Cloud service or on-device model that aggregates the sensor data, image and answers, then calls DeepSeek, ChatGPT and Google AI to return: – Symptom analysis – Risk level visualisation – Personalised plan (diet, lifestyle, TCM tea recipe) • Admin dashboard for me to review anonymised data and refine the AI prompts. Acceptance criteria will be met when I can pair a watch, capture a tongue image, answer questions and receive a coherent, actionable report in under one minute.
