Four components that fully automate your calendar
Self-service Booking
Clients access your booking link, see available slots in real time, and confirm their reservation in seconds. No calls, no messages, no manually managed waiting lists. The booking page is fully customizable with your business branding.
Google / Outlook Sync
Two-way sync with Google Calendar and Microsoft Outlook. Appointments from 4appointments appear automatically in each specialist's personal calendar — and blocked time in Google is respected automatically, no duplicates.
Recurring Appointments
Set it once — weekly, biweekly, or a custom interval — and the system automatically generates the entire series. Clients receive confirmation for each, with the option to modify a single occurrence or the whole series.
