Clinic Appointment Book with No-Show Count and Recall List

Clinic Appointment Book is an offline app (one HTML file in a zip). You enter your doctors with their working hours, your treatments with the minutes they need, and your patients. Each appointment is checked when saved: the doctor must be free, inside working hours, and the slot long enough for the treatment. The desk shows today, tomorrow's patients to remind, patients who missed appointments before, and patients who are due back.

The problem it removes: Bookings arrive on the phone and on WhatsApp and the day ends in double bookings, patients who did not come, and empty chairs. Nobody counts who misses appointments again and again, and patients who needed a six month check-up are only remembered when they happen to call. This app checks each booking against the doctor's time and keeps the count and the recall list for you.

What is inside:

• Doctors with room and working hours, and treatments with the minutes they need and a flag for a recall interval
• Appointments that refuse an overlap with the same doctor, a slot outside working hours or shorter than the treatment needs
• A diary calendar, a Front desk page with today, tomorrow's reminder list and WhatsApp links
• A missed appointment count per patient: after the limit you set, a new booking needs a note on who confirmed it
• No-show rate by doctor and by month, and a printable list of missed appointments
• A recall list: patients whose last completed visit was longer ago than their recall interval, with a reminder link, and not already booked
• Printable appointment slip (A5), day list and recall list
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: front desk staff and practice managers in small clinics who book by phone and WhatsApp and keep the diary on paper or in a spreadsheet.

What it is NOT: It is not a medical record and has no place for diagnoses, notes or images: do not type medical details. It does not send messages, it opens WhatsApp with the message ready. It does not bill patients or claim from insurers, and it does not know what your clinic or its licence allows. Working hours and limits are what you enter. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (166 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1232 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
