Gaplets

Appointment waitlist automation — auto‑fill last‑minute cancellations

Gaplets detects openings on Square Appointments, messages eligible clients via SMS/Email, and auto‑books the first to confirm — turning empty slots into revenue.

No credit card. Works with Square Appointments.

📅

Appointment cancellation detected

3:00 PM with Dr. Roberts is now available.

Notification sent to 8 eligible clients

Gaplets selects clients based on availability, service match, and past reliability, then notifies them via SMS/Email.

"Reply YES to confirm."
"Hi! An appointment just opened up at 3:00 PM. Would you like to take it?"
The silent leak

Cancellations quietly drain your month

Cancel the slot and our appointment waitlist app handles detection, notifications, and auto-booking — end-to-end.
