The Challenge

Medication management for elderly is error-prone

Dangerous drug interactions go unnoticed

Paper schedules are hard to digitize

Multiple stakeholders (patient, family, social worker, doctor) need different views

Must work offline (poor connectivity in rural areas)

Solution

Medication Safety Engine

40+ drug interaction rules (critical / warning / info levels). Thyroid-calcium, bisphosphonate-calcium, warfarin, and more. Real-time alerts when adding medications.

Drug interaction warnings — critical and warning level alerts for medication conflicts

Solution

AI-Powered Schedule Scanning

Gemini Vision OCR for paper medication schedules. Extracts medication name, dosage, frequency, timing. Automatic import into digital schedule.

Medicine Cabinet — AI-powered medication inventory with Scan Schedule feature

Solution

Multi-Role Dashboards

Patient: personal meds, adherence, vitals. Caregiver: family member oversight. Social Worker: client monitoring. Doctor: adherence statistics.

Patient — daily schedule, next intake countdown, adherence score, Fitbit heart rate

Caregiver — monitors multiple family members, FCM push alerts on missed doses

Social Worker — client list with adherence status, flags clients needing follow-up

Doctor — adherence statistics and trends across patients, read-only access

Try Demo As — User, Caregiver, Social Worker, Doctor role selection

Solution

Offline-First Architecture

Service Worker with sync queue. Works without internet. Background sync when connectivity returns. Medication logs are written locally first, then synced to Firestore when the connection is restored. No data is lost.

Weekly medication schedule — works offline with service worker sync

Solution

Adherence Engine

Timezone-aware medication tracking. Adherence scoring and trends. Fitbit integration for health data.

Analytics dashboard — Treatment Adherence 30-day chart and Meds vs Pulse correlation
