The challenge

Appointments were booked by phone and written into diaries at each clinic. Double bookings happened, gaps went unfilled, and missed appointments wasted doctors' time.

Patients could only book during reception hours.

Our approach

  1. Model real schedules

    Doctor availability, appointment types and clinic hours were configured per location.

  2. Let patients book themselves

    Patients see live slots and book in a few taps, at any hour.

  3. Reduce no-shows

    Automatic reminders and optional advance payment encourage attendance.

  4. Support reception

    A staff dashboard handles walk-ins, changes and daily schedules.

The solution

Patients now book, reschedule and pay through the app, seeing only genuinely available slots. Reminders reduce missed appointments.

Reception teams manage the day from one dashboard instead of diaries and phone calls.
