(01)The brief
What needed solving
Bookings happened over the phone while the receptionist answered the phone, so double-bookings and no-shows were both normal. Any app that only added another channel would have made the queue worse.
(02)Approach
How it was built
(01)
Slots derive from the doctor's real calendar, including the buffer the clinic needs — an app that shows a slot the desk cannot honour is worse than no app.
(02)
Booking is possible without an account; registration can happen after the appointment exists.
(03)
Reminders one day and two hours ahead, with a tap to confirm or cancel, so a freed slot comes back into the pool.
(04)
Reception keeps a manual override for walk-ins, because removing their control is how these projects fail.
(03)Outcome
What changed
The phone stops being the only path into the calendar. Patients see the same slots the desk sees, cancellations return to inventory, and the clinic has a record of attendance it never had before.
