For specialists, family doctors, nurse practitioners, dentists and allied health, anywhere in the world
Fill cancelled appointments with patients who are already nearby.
Within the Hour is a cancellation-list app for clinics. Create a list, share a QR code, and when a slot opens, notify patients within range. The first to accept takes the spot. Works in any country. Free for 3 months. No EMR integration needed.

Patient? Download the app, then scan your clinic's QR code or enter its WTH# to join the list. How it works for patients


How It Works
Set up in minutes, on the web or in the app.
Every account includes a cancellation list and a check-in list.
Cancellation list
Fill last-minute openings.
Create a list or service.
Set up your account in the app or in the web app, then create a list for each service you offer.
Share to patients using the QR code or WTH# for your list.
Print it at reception or add it to appointment reminders. Patients join in seconds.
When you have extra time send out a notification.
See the patients who’ve accepted your last-minute invite.
Create a check-in list.
One for your clinic or for each service. Free on every account.
Patients check in at reception.
They scan the QR code or enter the WTH#, and join the list in the order they arrive.
They come back when their turn is near.
Patients wait wherever suits them, a café or their car, and get a notification when it’s almost their turn.
Less phoning around for your front desk.
Today, staff phone, text or email patients one at a time, or let the opening go unused. With WTH your team still sends the opening; the app reaches everyone nearby at once, collects the acceptance and shows who is coming.
- Notifications are sent to patients who are nearby and can arrive on time.
- Patients on the list within range will receive a push notification and can accept or decline the appointment directly from the app.
- Providers can easily manage available slots and track appointments filled through the app.
Two ways clinics use it
Fill cancellations, or empty the waiting room.
Most clinics need one or the other. Both come with every account.
“We spend forever trying to fill cancellations.”
Cancellation Lists
Anytime slots are available you can send a notification to patients within a specific range of your clinic. Patients on the list within range will receive a push notification and can accept or decline the appointment directly from the app.
Best for: specialists, family practices, dentists, allied health and diagnostic services with long waitlists or frequent cancellations.
“Our waiting room is always packed.”
Check-in (Sequential) Lists
A sequential list allows patients to join a waitlist in the order they sign up. This feature is handy for those patients who might come onsite to a clinic and wish to leave and come back when they might be seen.
Best for: busy, crowded waiting rooms with unpredictable or long waits, where stable patients can safely leave and come back.
Who it's for
Any practice that loses appointments to last-minute cancellations.
Specialists and surgeons
Long waitlists, scarce capacity, every slot matters. The strongest fit.
Family doctors and nurse practitioners
Same-day cancellations and patients who would come sooner if asked.
Dentists and allied health professionals
Hygiene, emergency and treatment slots that open at short notice.
Diagnostics, labs and hospital clinics
Imaging, tests and outpatient clinics where every booked hour counts.
Before you ask
No integration. No monthly fee. No surprise bills.
Can I integrate Within the Hour with my existing EHR system?
No. WTH can best serve your needs by being strongly and securely independent. By eliminating integration with third party software such as EMRs we are able to improve cybersecurity, maintaining the core relationship between providers and patients.
How do I notify patients about last-minute openings?
Anytime slots are available you can send a notification to patients within a specific range of your clinic. Patients on the list within range will receive a push notification and can accept or decline the appointment directly from the app. You will only be charged if they accept an appointment.
Do I need to pay to use “Within the Hour”?
The app is free to download and use for patients. Your provider may choose to pay to use the app.
Is my information safe?
Yes. The app follows strict privacy standards, including HIPAA compliance and is monitored by Vanta for security. The app doesn’t need your medical information, just your name and birthdate.

Why we built it
Fourteen Years of Training — and an Empty Chair
Dr. Alex de Saint Sardos, surgeon and founder of Within the Hour
“It takes about fourteen years of university and postgraduate medical training to become a specialist. And yet, some days, I sit there with an empty chair. Not because there aren’t patients who need to see me. There are hundreds. But someone cancelled this morning, and now I have twenty minutes.”
Alex built Within the Hour inside his own specialist clinic, to fill those twenty minutes without tying up his front desk. Read the founder's story
