abstract = {Chronic non-communicable diseases (NCDs) principally Type 2 diabetes mellitus, hypertension, and cardiovascular disorders affect more than 1.3 billion individuals globally and account for 74% of all deaths worldwide. In India, over 101 million individuals live with diabetes and approximately 220 million suffer from hypertension, yet the national doctor-to-patient ratio stands at a critically inadequate 1:1,456. Existing digital health solutions either depend on prohibitively expensive wearable hardware or deliver narrow, non-personalised monitoring devoid of emergency response capability. This paper presents Aarogya Mitra: Health Coach AI, a wearable-free, AI-driven mobile health platform providing continuous, personalised chronic disease management using only a standard smartphone. The system integrates six modalities motion signals, GPS, manual vitals, HealthKit data, medical OCR, and behavioural context through a unified sense–analyse–act–learn pipeline. A hybrid CNN–LSTM architecture trained on 30–60 second sliding windows models biosignal patterns; a Random Forest ensemble of 100 decision trees provides personalised anomaly detection; and a RAG-enhanced LLaMA-3-8B-Instruct conversational agent grounded in WHO and ICMR clinical guidelines delivers context-aware health coaching with multilingual support for 5+ Indian languages. An OCR Smart Cam module digitises prescriptions and lab reports to 93% accuracy. A real-time SOS fall-detection subsystem dispatches emergency alerts within 10 seconds. Evaluated across the PhysioNet MIT-BIH Arrhythmia, WESAD, and DEAP benchmark datasets alongside an 8-week controlled pilot study (n=47 in the IJIRT paper; n=50+ in beta trials), Aarogya Mitra achieved 95.2% bio signal classification accuracy (AUC-ROC: 0.991), 96.1% ensemble accuracy, 93% OCR extraction accuracy, and 98% SOS alert success rate. A 2-month beta trial (n=50+) demonstrated a 68% improvement in medication adherence, 91% weekly engagement, and a 30% reduction in emergency hospital visits, yielding a user satisfaction score of 4.3/5.},
