Why Healthcare Providers Need a Digital Consultation Platform
The gap between patients who need a doctor and doctors who could help them is largely a logistics problem — one that telemedicine solves completely.
Indians underserved by in-person doctor access in Tier 2, 3, and rural India — who could be reached instantly via a telemedicine app
No-show rate for in-person appointments; video consultation reduces no-shows to under 10% — freeing up clinical time for patients who truly need in-person visits
saved per patient per visit by replacing routine in-person follow-up consultations with video calls — without reducing the quality of care
Patients Can't Reach You After Hours
Most patient queries happen outside clinic hours — medication doubts, post-surgery symptoms, prescription renewals. Without a digital channel, patients go to emergency rooms or ignore symptoms. A telemedicine app gives them access when they actually need help.
Geography Limits Your Patient Base
A specialist in Ahmedabad can only see patients who physically travel to them. Telemedicine removes the geography barrier entirely — reach patients in Rajkot, Surat, or rural Gujarat from your desk. Your expertise is no longer limited to your city.
Paper Prescriptions and Records Get Lost
Patients lose paper prescriptions. Medical history is scattered across clinics, labs, and hospitals in paper form. A shared digital record linked to every consultation gives both patient and doctor an accurate, always-accessible clinical history.
No Continuity of Care
Without a shared platform, follow-up is ad-hoc — a phone call or WhatsApp message. A telemedicine app structures follow-up: scheduled video calls, automated appointment reminders, and linked prescription and lab history from every previous visit.
Doctor Panel & Patient App — Complete Feature Set
Two fully separate experiences — one built for doctors managing their practice, one built for patients who need care.
Doctor Panel Features
Appointment Management
Set available slots, manage video vs in-person appointments, handle rescheduling and cancellations. Buffer time between appointments configurable per doctor. View day/week schedule at a glance.
Video Consultation
WebRTC end-to-end encrypted video calls directly in the app. Waiting room with admit/reject control. Mute, camera, and screen-share controls. Prescription can be drafted and issued during the call without leaving the screen.
Digital Prescriptions
Issue PDF prescriptions signed with doctor credentials after each consultation. Linked to the patient's complete medical history. Pharmacy delivery integration optional. Patients download prescriptions directly from their app.
Patient History Access
Full consultation history, past prescriptions, uploaded lab reports, and patient-entered symptoms — all visible before the consultation begins. Doctor walks into every appointment fully informed.
Secure In-App Chat
Text and image-based chat for follow-up queries between appointments. All communication stays in the encrypted platform — no WhatsApp, no public messaging apps. Chat history linked to the patient's clinical record.
Earnings Dashboard
View consultation fees collected, pending payouts, consultation count by day/week/month, and patient rating summary. Payouts via Razorpay automated settlement directly to the doctor's bank account.
Patient App Features
Find a Doctor
Search by specialisation, language, availability, and rating. Doctor profiles with qualification, experience, consultation fee, and verified patient reviews. Filter by available today, by fee range, or by city.
Book Appointment
Book video or clinic visit directly from the app. Pre-consultation symptom form helps the doctor prepare. Appointment confirmed with calendar invite and push notification reminder 30 and 5 minutes before the call.
Upload & Share Lab Reports
Upload blood tests, X-rays, or scans from phone camera or gallery. Share reports with the doctor before or during consultation for informed diagnosis. Reports stored securely and accessible in patient history.
Case Study: Linkmind — Our Live Doctor-Patient Consultation App
Linkmind is a production telemedicine app built by TechEinHub, with specialist doctors onboarded and live paid consultations running across India.
The Challenge
Healthcare startup needed a telemedicine platform for specialist consultations in India — with real video calling (not just chat), digital prescriptions, patient health records, and DPDP-compliant data architecture. The platform needed to support multiple specialist doctors from day one, each with their own schedule, fee, and earnings.
What We Built
Flutter app (iOS + Android) for patients, web portal for doctors (React.js), Python/Django REST API, end-to-end encrypted WebRTC video, Firebase for real-time chat, Razorpay for consultation fees and automated doctor payouts, S3-compatible encrypted storage for lab reports.
DPDP Compliance Approach
Patient data stored in AWS Mumbai region. All health records encrypted with patient-specific keys. Full consent management at registration with granular permissions per data type. Automated data deletion pipeline processes patient deletion requests within 72 hours as required.
The Result
Linkmind is live with multiple specialist doctors onboarded across India, processing paid consultations daily. Doctors manage their own schedules and receive automated payouts. Patients access their complete consultation history from the app. Read the full Linkmind case study →
Built to India's Health Data Privacy Standards
Patient health data is sensitive personal data under India's DPDP Act 2023. We build DPDP compliance into every telemedicine app from the first line of code — not as an afterthought.
Data Stored in India
Patient health records, consultation history, prescriptions, and lab reports stored exclusively on AWS Mumbai or GCP Mumbai region. No health data transferred outside India.
Encrypted Health Records
All patient records encrypted at rest using AES-256. Video calls encrypted end-to-end via WebRTC DTLS-SRTP. Lab reports stored with patient-specific encryption keys.
Consent Management
Patients give explicit, granular consent for each type of data processing at registration. Consent is logged with timestamp. Patients can withdraw consent and request full data deletion at any time — fully automated.
DPDP Act 2023 Ready
Data minimisation, purpose limitation, and data principal rights (access, correction, deletion) — all implemented. Audit logs for every data access operation. Ready for DPDP compliance certification.

Get a Custom QuoteFrequently Asked Questions
Questions healthcare clients ask us most often before starting a telemedicine project.
Is the doctor-patient app DPDP compliant?
Yes. Every healthcare app we build follows the Digital Personal Data Protection (DPDP) Act 2023. Patient health data is encrypted at rest and in transit, stored only in Indian data centres, never shared with third parties, and patients have full rights to access and delete their data. We implement consent management as per DPDP requirements for sensitive health information — this is not an add-on, it's built in from the architecture stage.
How does video consultation work in the app?
We integrate WebRTC-based video calling directly into the app — no third-party app needed. Patients book an appointment, join the waiting room in-app, and the doctor is notified when the patient is ready. The video call is end-to-end encrypted. Video quality adjusts automatically based on network speed — the call remains clear even on 3G connections. Consultations can be recorded with patient consent for future reference.
Can doctors issue digital prescriptions?
Yes. After each consultation, doctors can issue a digital prescription with medication name, dosage, frequency, and duration — directly from the consultation screen without switching apps. Prescriptions are signed with the doctor's credentials, downloadable as PDF by the patient, and stored in the patient's health record linked to that consultation. Pharmacy delivery integration is also available.
Can multiple specialists use the same platform?
Yes. The platform supports multiple doctors across any number of specialisations — each with their own appointment schedule, consultation fee, patient list, and earnings dashboard. Patients can search by specialisation, availability, and rating. The admin panel manages doctor onboarding, credential verification, and platform-level analytics across all doctors.
How long does it take to build a telemedicine app?
A telemedicine app with video consultation, chat, appointments, and prescriptions typically takes 16–22 weeks. A basic appointment booking app without video can launch in 10–12 weeks. Timeline depends on integrations needed — payment gateways, lab report upload, pharmacy tie-ups, and insurance billing each add 2–4 weeks to the scope.
