Appointment Reminder App gives clinics, labs and service businesses in India an appointment calendar and online booking page. Every booking gets WhatsApp reminders with Confirm, Reschedule and Cancel buttons that update the calendar, an SMS on your DLT template if WhatsApp fails and an AI call in Tamil, Hindi or English if the patient still has not confirmed.

Bookings from your online booking page, the front desk, a CSV list or your software each get a WhatsApp confirmation and reminders 24 and 2 hours before. No broadcast to schedule, no list to export.
Patients tap Confirm, Reschedule or Cancel on WhatsApp, or reply YES in their own language. The appointment changes status and a cancelled slot is offered to your waitlist.
WhatsApp undelivered? An SMS goes out on your DLT template. Still unconfirmed three hours before? An AI call in Tamil, Hindi or English asks, and the answer lands in the calendar.
Automatic for every booking, whichever way it was made. Each step is skipped for patients who opted out.
Beyond reminders
Each doctor, counter or home-collection team gets a calendar with working hours. Patients book on your online booking page, staff book in seconds, and bookings also arrive by CSV, webhook or API. Every booking gets a WhatsApp confirmation and reminders 24 and 2 hours before, with no broadcast to set up.
Why it matters: Clinics without an EMR finally get booking and reminders in one place, and clinics with one keep using it while reminders run here.
Reminders carry three WhatsApp quick-reply buttons. A tap confirms the visit, cancels it or sends the patient a link to pick a new slot themselves. Plain replies such as YES, ஆம் or हाँ work too, in nine languages.
Why it matters: Your front desk sees who is coming without making a single call, and the confirmation rate becomes a number you can track.
If a WhatsApp reminder fails or is not delivered within 15 minutes, the patient gets one SMS on your DLT-registered template with a confirm-or-change link. If they still have not confirmed three hours before the visit, the AI calls them in their language and records the answer.
Why it matters: Older patients and feature-phone users are the ones who miss visits; the escalation reaches them without your staff dialling.
When a patient cancels, the freed slot is offered on WhatsApp to the first matching person on your waitlist with a "Book this slot" button. If they do not take it in 30 minutes, the next person is offered it. Completed visits can schedule a recall reminder and a feedback request.
Why it matters: A cancellation stops being lost revenue, and follow-up visits and repeat tests stop depending on memory.
Services can require an advance: the UPI link goes out with the booking confirmation and stays in every reminder until paid. For dues, a payment request follows up on WhatsApp, then SMS, then an AI call, then your team, and stops as soon as the payment webhook confirms payment.
Why it matters: Patients who have paid an advance turn up; overdue bills are followed up without awkward calls by staff.
Confirmations and reminders go out in English, Tamil, Hindi, Telugu, Kannada, Malayalam, Marathi, Bengali or Gujarati. The app learns each patient's language from the script they reply in, and the AI voice speaks Tamil, Hindi and English.
Why it matters: A reminder in the patient's own language gets read and answered; US-built tools do not offer Indian languages.
Every opt-in and opt-out gets a DPDP Act 2023 consent receipt the patient can open. STOP replies are honoured on every channel, promotional SMS skips DND numbers, SMS needs a DLT template ID and calls stay inside your calling hours. ABHA numbers can be stored on the patient record.
Why it matters: Reminders that a carrier blocks never reach the patient, and you keep the evidence if anyone asks. Your DLT, Meta and ABDM registrations stay yours.
See the confirmation rate and no-show rate by doctor, branch, confirmation channel, patient language and booking source, plus reminder delivery, SMS fallbacks, AI calls, waitlist refills and advances collected. Export to CSV any time.
Why it matters: You find out which doctor, slot or language needs attention, and what the reminders are worth, from your own numbers.
