Slotly
Clients pick the service, the person and a free slot themselves, and reminders go out automatically the day before and two hours ahead.
Appointment Booking App for Salons and Clinics
A staff calendar shows the whole day or week, and a new appointment is one click on a free slot. Clients can also book themselves on a page on your website - they choose the service, the person and a free time, and the booking appears in the calendar right away. Email and SMS reminders go out on their own, so fewer slots stay empty.

What the app does
Calendar per staff member
Day and week views with a column for each person. Click a free slot to book, and the app blocks double bookings.
Online booking for clients
A page on your website where clients choose the service, the person and a free time. Only truly available times within opening hours are shown.
Automatic reminders
Email and SMS 24 hours and 2 hours before the appointment, in your own words with the booking details filled in. Fewer no-shows without a single call.
Client records
Visit history, total spent, no-shows and notes for every client. You see at a glance who is a regular and who often cancels.
