Core Capabilities

Zero-Cloud Offline Engine STATUS: 100% AIR-GAPPED CAPABLE Built strictly to W3C Progressive Web App standards with high-resilience Service Worker caching (sw.js). Runs identically across Android, Apple iOS, Windows, macOS, and Linux desktop browsers. Fully operational in basements, transit, or rural zones with zero cellular connectivity.	Jan Aushadhi & NLEM Formulary STATUS: 145+ FORMULATIONS INCLUDED Comprehensive catalogue containing 145+ essential medicine formulations including 33 Pradhan Mantri Bhartiya Janaushadhi Pariyojana (PMBJP) generic salts. Features two-way generic-to-brand mapping and progressive OpenFDA online medicine discovery with automatic IndexedDB caching.
Calendar Adherence History STATUS: MONTHLY MATRIX & STREAK TRACKING Interactive month-by-month compliance calendar visualizing full adherence, partial compliance, and missed doses. Select any calendar day to inspect an itemized log of taken routines with patient chips, exact dosage timestamps, and clinical food timing.	Natural Accent Speech Synthesis STATUS: EN / HI / TE VOICE CALIBRATED Dedicated speech prioritization configured for natural Indian phonetics. Prioritizes Microsoft Aarti Online, Apple Rishi, and Google Indian phonetics with normalized 0.88x cadence and 1.04 pitch for elderly auditory clarity in English, Telugu (తెలుగు), and Hindi (हिन्दी).
Harmonic Web Audio Chimes STATUS: D5 - A5 - D6 RESONANCE Zero-file Web Audio API algorithmic chime generator. Synthesizes gentle tri-tone acoustic alerts (587 Hz → 880 Hz → 1175 Hz) with natural exponential decay ramps, replacing jarring phone alarms with soothing clinical reminders.	WhatsApp Pharmacy Refill Dispatcher STATUS: 1-TAP STANDARDIZED ORDER Compiles pending shortages and depleted stock into clean, standardized WhatsApp order strings formatted for immediate transmission to neighborhood chemists or delivery services without manual typing.
On-Device Packaging OCR Engine STATUS: CLIENT-SIDE TESSERACT.JS HTML5 Canvas pre-processing normalizes contrast and applies adaptive binarization before client-side Tesseract.js optical character recognition extracts brand names and salt strengths without transmitting packaging photos to external servers.	Ergonomic Accessibility Settings STATUS: TEXT SCALING & ROLE CONTROL Configurable text sizing (Standard 15px, Medium 17px, Large 19px) specifically tailored for senior vision accessibility, combined with multi-role access modes (Caretaker, Adult Member, Senior Patient).
