How to start
Tell us what you need in your own words. You talk to the developers who would build it and get a written, line-item estimate.
Get a project estimateDesigned for how Indian OPDs run
Many clinics in India run on tokens rather than fixed slots. Doctors arrive after hospital rounds, consultations vary from three minutes to thirty, and many patients simply walk in. A doctor appointment app that pretends every visit is a fifteen-minute slot creates more confusion, not less.
We support both models. Slots suit dentists, physiotherapists and specialists with predictable visits; tokens with a live "now serving" status suit busy general physicians and paediatricians. Patients see an estimated turn time and get a WhatsApp nudge when it is close. The reception console merges online, phone and walk-in patients into one queue.
Challenges
Front-desk problems an appointment app fixes
Crowded waiting rooms
Live queue status and "your turn is near" alerts let patients arrive closer to their time.
Doctors at several locations
One schedule that every clinic reception can see, for doctors who move between clinics.
Delayed or cancelled sessions
Booked patients are told and offered alternatives automatically when a doctor is late or on leave.
Registration at the counter
Pre-registration in the app, or ABDM's Scan and Share where supported, shortens the queue.

How it works
How a clinic visit flows with tokens and a live queue
Online, phone and walk-in patients end up in one queue that everyone can see.
- Patient app or website
Step 1: Patient books a slot or token
The patient, or a relative, chooses a doctor and session, books a slot or token and can pay the fee online.
- WhatsApp and patient app
Step 2: Reminder and live queue
On the day, the patient sees which token is being served and gets a nudge when their turn is near.
- Reception console
Step 3: Check-in at reception
Online, phone and walk-in patients join one queue; reception checks them in, records vitals and prints a token.
- Doctor view
Step 4: Consultation
The doctor calls the next patient from the queue and sees previous visits and prescriptions.
- Doctor view and patient app
Step 5: Prescription and follow-up
The prescription is saved to the visit, and a follow-up date within the free revisit window is suggested.
- Admin
Step 6: Reports for the clinic
Waiting times, no-shows and sessions per doctor show where the schedule needs adjusting.
Platforms
Where patients book and clinics run the queue
Patients use an app or the clinic website; reception uses a tablet or desktop, and a TV shows the current token.

Plain-English glossary
Clinic booking terms, in plain English
- Token system
- Patients get a number in the order they book or arrive, and the doctor sees them in sequence. It suits busy OPDs where consultations vary in length.
- Estimated turn time
- A time range, worked out from the doctor's actual pace and the queue ahead, that tells a patient roughly when to arrive. It updates as the queue moves.
- Scan and Share
- An ABDM feature where a patient scans a QR code at the counter to share their ABHA profile, so reception does not type in their details.
- DLT-registered SMS
- SMS messages in India must use templates registered on the telecom operators' DLT platform. We register reminder templates so fallback SMS actually reach patients.
- Free revisit window
- A period after a consultation when a follow-up is free or charged less. The system checks it automatically at booking and billing.
Product preview
Patient app, reception console and waiting-room display
Patient app. Patients follow the live queue from home and leave when their turn is near, which keeps the waiting room less crowded. 
Reception console. Reception manages online, phone and walk-in patients in one queue, records vitals and prints tokens without a separate register. 
Waiting-room display. A TV in the waiting room shows the current token for each doctor, so patients stop asking reception about their turn. 
Clinic reports. Clinic owners see waiting times, no-shows and booking channels per doctor, which helps them adjust sessions and staffing.

Cost drivers
Scope and cost factors for appointment apps
Slots, tokens or both
Both models with live queue estimates take more work than fixed slots alone.
Clinics and doctors
Multi-location schedules and central reporting add admin complexity.
Hospital system sync
Syncing with existing hospital software depends on its API and often sets the timeline.
Prepayment and refunds
Online fees with automatic refunds and settlement reports add work.
Estimates are written from your scope, with the effort and assumptions behind each line item.

FAQ
Frequently asked questions
Should our clinic use time slots or tokens?
It depends on how predictable consultations are. If most visits take a similar time, as with physiotherapy or dental follow-ups, slots work well. If durations vary widely and walk-ins are common, tokens with an estimated turn time are more honest. Many clinics mix them, with a few bookable slots at the start of a session and tokens after, and different doctors can use different models.
How is the estimated waiting time calculated?
It uses the doctor's actual start time, the token being served, patients checked in ahead and a rolling average of that doctor's recent consultation durations. The estimate appears as a range and updates as the queue moves. An emergency or complex case can still hold up a session, so patients are notified when their turn moves significantly.
Can patients book appointments for elderly parents or children?
Yes. One mobile number can hold several family profiles, each with its own visit history and prescriptions. A caregiver can book, receive reminders and view records for the family members they manage, while adult members can be asked to confirm that access. This matches how many Indian families use healthcare, with one person coordinating visits for parents, children and in-laws.
Will the app work with the software our clinic already uses?
If your current software has an API, the app can sync doctors, slots and registrations with it, so reception keeps its familiar system. If not, our reception console can become the scheduling system while billing stays where it is, or the old software can be replaced entirely. We review your setup in discovery and recommend the least disruptive route.
